chore: 2.4.3

模型在未通过 SearchExtraTools 发现工具的情况下直接调用 ExecuteExtraTool，
因不知道工具 schema 导致参数错误（如 libraryName: undefined）。

双重修复：
1. ExecuteTool.call() 添加服务端拦截：检查目标 deferred 工具是否已被发现
2. 更新 <available-deferred-tools> 系统提示：要求先搜索再执行

 路径规则：统一用 `.ts` 扩展名 + `src/*` 别名路径，禁止双重 mock 同一模块。
 
+#### 跨文件 mock 污染（process-global `mock.module`）
+
+**Bun 的 `mock.module` 是进程全局的（last-write-wins），不是 per-file 隔离的。** 一个测试文件的 `mock.module` 会污染同一进程中所有其他测试文件的 `require`/`import`。
+
+**关键事实（Bun 1.x 实测验证）：**
+- 测试文件执行顺序**不是严格字母序**，不要假设文件 A 一定在文件 B 之前执行。
+- `mock.module` 在 `beforeAll` 内部调用时**不会被提升**（hoist），但仍会污染后续加载的文件。
+- `require()` 和 `import()` 共享同一模块注册表，`mock.module` 对两者都生效。
+- 一个模块一旦被某个文件的 `mock.module` 替换，同一进程中所有后续 `require`/`import` 都会返回 mock 值，即使调用方使用不同的 specifier 路径。
+
+**核心规则：不要 mock 被测模块的上层业务模块。**
+
+错误做法（会污染同目录的 `api.test.ts`）：
+```ts
+// launchSchedule.test.ts — 直接 mock 源 API 模块 ❌
+mock.module('src/commands/schedule/triggersApi.js', () => ({
+  listTriggers: listTriggersMock,
+  // ...
+}))
+```
+
+正确做法（mock 底层 HTTP 层，不污染业务模块）：参考 `launchSkillStore.test.ts`、`launchVault.test.ts` 的模式。
+```ts
+// launchSchedule.test.ts — mock axios 而非 triggersApi ✅
+import { setupAxiosMock } from '../../../../tests/mocks/axios.js'
+
+const axiosHandle = setupAxiosMock()
+axiosHandle.stubs.get = axiosGetMock
+axiosHandle.stubs.post = axiosPostMock
+
+beforeAll(() => { axiosHandle.useStubs = true })
+afterAll(() => { axiosHandle.useStubs = false })
+```
+
+**判断标准：** 如果目录下同时有 `launch*.test.ts`（集成测试）和 `api.test.ts`（回归测试），`launch*.test.ts` 必须 mock axios 而非源 API 模块。`api.test.ts` 需要测试真实 API 模块的 HTTP 方法/URL/错误处理逻辑，被 mock 后就无法测试。
+
+**排查 mock 污染的方法：**
+1. 单独运行可疑文件确认其通过：`bun test path/to/suspect.test.ts`
+2. 与同目录其他文件一起运行定位污染源：`bun test path/to/__tests__/`
+3. 在两个文件中各加 `console.error('[file] milestone')` 追踪实际执行顺序
+4. 检查 `mock.module` 的 specifier 是否与同目录其他测试的 `require`/`import` 路径解析到同一模块

-# Feature: 20260510_F001 - multi-encoding-file-tools
-
-## 需求背景
-
-当前文件读写工具（FileReadTool、FileWriteTool、FileEditTool）的编码检测非常简单——仅通过 BOM 头识别 UTF-8 和 UTF-16LE，其他所有情况默认按 UTF-8 处理。对于 GBK/GB2312 等非 BOM 编码文件，读取时会产生乱码，导致 AI 模型无法正确理解和编辑这些文件。
-
-这在中文 Windows 用户场景中尤其常见：许多旧项目、日志文件、配置文件使用 GBK 编码，当前工具链无法处理。
-
-## 目标
-
-- 文件读取时自动检测编码并正确解码，对 AI 模型完全透明（不增加 encoding 参数）
-- 文件写入时保持原文件编码，不改变用户的编码习惯
-- 覆盖 GBK 编码（最常见非 UTF-8 CJK 编码），latin1 作为最终兜底
-- 零外部依赖，仅使用 Node.js/Bun 内置的 TextDecoder/TextEncoder
-
-## 范围变更
-
-**仅保留 GBK 编码支持**。Shift_JIS、EUC-JP、EUC-KR、Big5、GB18030、ISO-8859-1 已移出范围。原因：多编码回退链存在字节序列歧义（如 GBK 和 Shift_JIS 共享大量有效字节范围），导致误检测。GBK 覆盖了最核心的中文 Windows 用户场景。
-
-## 方案设计
-
-### 架构概述
-
-新增一个独立的编码工具模块 `src/utils/encoding.ts`，提供编码检测和解码/编码函数。现有文件读写路径通过调用此模块实现对非 UTF-8 编码的支持。

-
-### 编码检测算法（三层检测）
-
-检测基于文件头部 4KB 数据，分三层依次判断：
-
-**第一层：BOM 检测（现有逻辑保留）**
-- `FF FE` → UTF-16LE
-- `EF BB BF` → UTF-8（带 BOM）
-
-**第二层：UTF-8 验证**
-- 用 `new TextDecoder('utf-8', { fatal: true })` 对头部 4KB 做解码
-- 成功 → 文件为 UTF-8（覆盖绝大多数现代源码文件）
-- 失败（抛出 TypeError）→ 进入第三层
-
-**第三层：GBK 回退**
-- 用 `new TextDecoder('gbk', { fatal: true })` 尝试解码头部 4KB
-- 成功 → 文件为 GBK（覆盖中文 Windows 用户最常见的非 UTF-8 编码）
-- 失败 → `latin1`（单字节编码，永远成功，作为最终兜底）
-
-```typescript
-// src/utils/encoding.ts 核心逻辑
-
-export type FileEncoding = BufferEncoding | 'gbk'
-export type DetectedEncoding = string
-
-export function detectEncoding(buffer: Buffer): FileEncoding {
-  // Layer 1: BOM
-  if (buffer.length >= 2 && buffer[0] === 0xff && buffer[1] === 0xfe) {
-    return 'utf-16le'
-  }
-  if (buffer.length >= 3 && buffer[0] === 0xef && buffer[1] === 0xbb && buffer[2] === 0xbf) {
-    return 'utf-8'
-  }
-
-  // Layer 2: UTF-8 validation
-  try {
-    new TextDecoder('utf-8', { fatal: true }).decode(buffer)
-    return 'utf-8'
-  } catch {}
-
-  // Layer 3: GBK fallback
-  try {
-    new TextDecoder('gbk', { fatal: true }).decode(buffer)
-    return 'gbk'
-  } catch {}
-
-  return 'latin1'
-}
-```
-
-### 读取路径改造
-
-#### `src/utils/fileRead.ts` — `detectEncodingForResolvedPath`
-
-将现有的 BOM-only 检测替换为调用 `encoding.ts` 的 `detectEncoding` 函数。返回值从 `BufferEncoding` 改为 `FileEncoding`（`BufferEncoding | 'gbk'`）。
-
-`readFileSyncWithMetadata` 函数先读 raw Buffer，再用 `decodeBuffer` 解码，而非使用 `fs.readFileSync` 的 encoding 选项（该选项只接受 `BufferEncoding`，不支持 `gbk`）。
-
-#### `src/utils/readFileInRange.ts` — 异步读取
-
-当前两个路径（fast path 和 streaming path）都硬编码 `encoding: 'utf8'`：
-
-**Fast path 改造**：
-- `readFile` 改为读取 Buffer（去掉 encoding 参数）
-- 读取后调用 `detectEncoding(buffer)` 检测编码
-- 用 `decodeBuffer` 解码为字符串
-- 后续行处理逻辑不变
-
-**Streaming path 改造**：
-- `createReadStream` 去掉 `encoding: 'utf8'`，改为 Buffer 模式
-- 第一个 chunk 做编码检测（同时保留 BOM 剥离逻辑）
-- 后续 chunk 拼接后用 `TextDecoder` 解码
-- 注意：streaming 路径需要特殊处理——先收集足够字节做检测，再逐行扫描
-
-**Streaming 编码处理策略**：
-streaming 路径改为两阶段：
-1. **检测阶段**：前 4KB 数据到达后立即检测编码
-2. **解码阶段**：用检测到的编码创建一个 `TextDecoder`（`{ stream: true }` 模式），逐 chunk 解码
-
-### 写入路径改造
-
-#### 编码回写策略
-
-写入时需要将内部 UTF-8 字符串编码回原文件编码。由于 `TextEncoder` 只支持 UTF-8 输出，需要使用 `TextDecoder` 的反向操作。
-
-**最终决定**：对于非 UTF-8 文件的写回，尝试使用 `Buffer.from(content, encoding)` 编码，失败则自动转换为 UTF-8 并在结果消息中注明。这样既满足了零依赖约束，也避免了数据损坏。
-
-#### `src/utils/file.ts` — `writeTextContent`
-
-现有函数签名 `writeTextContent(filePath, content, encoding, lineEndings)` 已接受 encoding 参数。需要：
-- 扩展类型，接受 `FileEncoding` 而非仅 `BufferEncoding`
-- 对于 UTF-8 和 UTF-16LE，行为不变
-- 对于 GBK，使用 `encodeString` 函数尝试编码，失败则回退为 UTF-8 写入
-
-#### `FileWriteTool` 和 `FileEditTool`
-
-这两个工具的 `call` 方法中，`writeTextContent` 调用已传递 `encoding`（来自 `readFileSyncWithMetadata` 的返回值）。改动很小——只需确保类型系统接受新编码名。
-
-### 类型扩展
-
-```typescript
-// 扩展编码类型 — 仅添加 GBK
-export type FileEncoding = BufferEncoding | 'gbk'
-```
-
-在 `readFileSyncWithMetadata` 返回类型中将 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`。
-
-## 实现要点
-
-### 关键技术决策
-
-1. **检测只用头部 4KB**：避免全文件扫描，性能开销极小（多几次 TextDecoder 调用，每次 ~1μs）
-2. **GBK 作为唯一回退**：中文 Windows 用户最多，且避免了多编码回退链的字节序列歧义问题
-3. **TextDecoder fatal 模式**：`{ fatal: true }` 是检测的关键——如果字节序列不符合编码规范会抛异常，借此区分不同编码
-4. **streaming 路径的两阶段设计**：先攒够检测数据再开始行扫描，避免半字符解码问题
-5. **latin1 最终兜底**：单字节编码永远成功，确保任何文件都能被读取
-
-### 难点
-
-1. **Streaming 编码解码**：`TextDecoder` 支持 `{ stream: true }` 模式处理多字节字符的 chunk 边界，但需要在检测完成前缓冲数据
-2. **编码回写的零依赖方案**：`TextEncoder` 只输出 UTF-8，非 UTF-8 编码回写需要额外处理。务实方案是 UTF-8 写入 + 消息提示
-3. **混合编码文件**：极少见，不在本次覆盖范围内
-
-### 依赖
-
-- 零外部依赖，仅使用 `TextDecoder`（Node.js 13+ / Bun 内置 full-icu）
-- Bun 运行时对 GBK 的 TextDecoder 支持已验证可用（Bun 1.3.13）

-### Task 1: 编码检测核心模块
-
-**背景:**
-当前 `src/utils/fileRead.ts` 的 `detectEncodingForResolvedPath` 仅通过 BOM 头识别 UTF-8 和 UTF-16LE，其他所有文件一律返回 `utf8`，导致 GBK 等非 UTF-8 编码文件读取乱码。本 Task 新建独立的编码检测工具模块 `src/utils/encoding.ts`，实现三层编码检测算法（BOM → UTF-8 fatal 验证 → GBK 回退），为后续 Task 2/3/4 的读写路径改造提供统一的编码检测和解码能力。本 Task 无前置依赖，是后续所有 Task 的基础。
-
-**涉及文件:**
-- 新建: `src/utils/encoding.ts`
-- 新建: `src/utils/__tests__/encoding.test.ts`
-
-**执行步骤:**
-
-- [x] 创建 `src/utils/encoding.ts`，定义类型
-  - 位置: 文件顶部
-  - 导出以下类型:
-    ```typescript
-    /** 扩展编码类型，覆盖最常见的非 UTF-8 CJK 编码 */
-    export type FileEncoding = BufferEncoding | 'gbk'
-
-    /** TextDecoder 接受的编码名（string），比 FileEncoding 更宽泛 */
-    export type DetectedEncoding = string
-    ```
-  - 原因: 后续 Task 2/3/4 需要这些类型来做编码标注和类型收窄
-
-- [x] 实现 `detectEncoding(buffer: Buffer): FileEncoding` 函数
-  - 位置: `src/utils/encoding.ts`，类型定义之后
-  - 三层检测逻辑:
-    ```typescript
-    export function detectEncoding(buffer: Buffer): FileEncoding {
-      // Layer 1: BOM 检测（与现有 fileRead.ts 逻辑一致）
-      if (buffer.length >= 2 && buffer[0] === 0xff && buffer[1] === 0xfe) {
-        return 'utf-16le'
-      }
-      if (
-        buffer.length >= 3 &&
-        buffer[0] === 0xef &&
-        buffer[1] === 0xbb &&
-        buffer[2] === 0xbf
-      ) {
-        return 'utf-8'
-      }
-
-      // Layer 2: UTF-8 fatal 验证
-      // fatal: true 模式下，无效 UTF-8 字节序列会抛出 TypeError
-      try {
-        new TextDecoder('utf-8', { fatal: true }).decode(buffer)
-        return 'utf-8'
-      } catch {
-        // 不是合法 UTF-8，进入 Layer 3
-      }
-
-      // Layer 3: GBK 回退
-      try {
-        new TextDecoder('gbk', { fatal: true }).decode(buffer)
-        return 'gbk'
-      } catch {
-        // 不是合法 GBK，latin1 作为最终兜底
-      }
-
-      return 'latin1'
-    }
-    ```
-  - 原因: BOM 必须优先于 fatal 验证；GBK 作为唯一回退避免了多编码链的字节歧义问题；latin1 单字节编码永远成功
-
-- [x] 实现 `decodeBuffer(buffer: Buffer, encoding: DetectedEncoding): string` 函数
-  - 位置: `src/utils/encoding.ts`，`detectEncoding` 之后
-  - 逻辑:
-    ```typescript
-    export function decodeBuffer(
-      buffer: Buffer,
-      encoding: DetectedEncoding,
-    ): string {
-      return new TextDecoder(encoding).decode(buffer)
-    }
-    ```
-  - 原因: 统一解码入口，后续 Task 2/3 的读取路径都调用此函数
-
-- [x] 实现 `encodeString(content: string, encoding: DetectedEncoding): { buffer: Buffer; converted: boolean }` 函数
-  - 位置: `src/utils/encoding.ts`，`decodeBuffer` 之后
-  - 逻辑:
-    ```typescript
-    export function encodeString(
-      content: string,
-      encoding: DetectedEncoding,
-    ): { buffer: Buffer; converted: boolean } {
-      if (encoding === 'utf-8' || encoding === 'utf8') {
-        return { buffer: Buffer.from(content, 'utf-8'), converted: false }
-      }
-      if (encoding === 'utf-16le') {
-        return { buffer: Buffer.from(content, 'utf-16le'), converted: false }
-      }
-
-      // 其他编码（如 gbk）：尝试 Buffer.from，失败则回退为 UTF-8
-      try {
-        const buf = Buffer.from(content, encoding as BufferEncoding)
-        return { buffer: buf, converted: false }
-      } catch {
-        return { buffer: Buffer.from(content, 'utf-8'), converted: true }
-      }
-    }
-    ```
-  - 原因: `Buffer.from` 在 Bun 中可能支持 GBK 编码名，但 Node.js 不支持。try-catch 策略兼容两种运行时；`converted` 标志让 Task 4 的写入路径能向用户报告编码转换
-
-- [x] 为编码检测和解码函数编写单元测试
-  - 测试文件: `src/utils/__tests__/encoding.test.ts`
-  - 测试场景:
-    - **BOM 检测 — UTF-16LE**: 输入 `Buffer.from([0xff, 0xfe, 0x48, 0x00])` → 预期返回 `'utf-16le'`
-    - **BOM 检测 — UTF-8 BOM**: 输入 `Buffer.from([0xef, 0xbb, 0xbf, 0x48, 0x65])` → 预期返回 `'utf-8'`
-    - **UTF-8 验证**: 输入 `Buffer.from('Hello, 世界', 'utf-8')` → 预期返回 `'utf-8'`
-    - **GBK 检测**: 输入 `Buffer.from([0xc4, 0xe3, 0xba, 0xc3])` → 预期返回 `'gbk'`
-    - **空 buffer**: 输入 `Buffer.alloc(0)` → 预期返回 `'utf-8'`
-    - **latin1 兜底**: 输入随机字节 `Buffer.from([0x80, 0x81, 0x82, 0x83, 0x84, 0x85])` → 预期返回 `'latin1'`
-    - **BOM 优先于内容分析**: 输入带 UTF-8 BOM 的数据 → 预期返回 `'utf-8'`
-    - **decodeBuffer — UTF-8**: 输入 UTF-8 编码的 buffer + encoding `'utf-8'` → 预期返回正确的中文字符串
-    - **decodeBuffer — GBK**: 输入 GBK 编码的 buffer + encoding `'gbk'` → 预期返回正确的中文字符串
-    - **decodeBuffer — UTF-16LE**: 输入 UTF-16LE 编码的 buffer + encoding `'utf-16le'` → 预期返回正确字符串
-    - **decodeBuffer — 空 buffer**: 输入空 buffer → 预期返回空字符串
-    - **encodeString — UTF-8**: 输入字符串 + encoding `'utf-8'` → 预期 `{ converted: false }`
-    - **encodeString — utf8 别名**: 输入字符串 + encoding `'utf8'` → 预期 `{ converted: false }`
-    - **encodeString — UTF-16LE**: 输入字符串 + encoding `'utf-16le'` → 预期 `{ converted: false }`
-    - **encodeString — GBK**: 输入字符串 + encoding `'gbk'` → 预期返回有效的 Buffer（converted 视运行时而定）
-  - 运行命令: `bun test src/utils/__tests__/encoding.test.ts`
-  - 预期: 所有测试通过
-
-**检查步骤:**
-
-- [x] 验证 `encoding.ts` 文件存在且导出正确
-  - `grep -c "export" src/utils/encoding.ts`
-  - 预期: 输出 >= 4（至少导出 FileEncoding, DetectedEncoding, detectEncoding, decodeBuffer, encodeString 共 5 个导出）
-
-- [x] 验证类型检查通过
-  - `bunx tsc --noEmit src/utils/encoding.ts 2>&1 | head -5`
-  - 预期: 无类型错误输出
-
-- [x] 运行编码检测单元测试
-  - `bun test src/utils/__tests__/encoding.test.ts`
-  - 预期: 所有测试通过，无失败用例
-
-**认知变更:**
-- [x] [CLAUDE.md] `src/utils/encoding.ts` 是文件编码检测的唯一入口，提供 `detectEncoding`（三层检测：BOM → UTF-8 fatal → GBK 回退）和 `decodeBuffer`/`encodeString` 函数。检测基于文件头部 4KB，零外部依赖，仅使用 TextDecoder API。`FileEncoding` 类型为 `BufferEncoding | 'gbk'`，覆盖最常见非 UTF-8 CJK 编码。latin1 作为最终兜底编码（单字节编码永远成功）。

-### Task 2: 同步读取路径集成
-
-**背景:**
-当前同步读取路径（`fileRead.ts` → `file.ts` → `fileReadCache.ts`）的编码检测仅通过 BOM 头识别 UTF-8 和 UTF-16LE，非 BOM 编码文件一律按 UTF-8 读取导致乱码。本 Task 将 `detectEncodingForResolvedPath` 的内部实现从 BOM-only 升级为调用 Task 1 创建的 `encoding.ts` 三层检测，并将返回类型从 `BufferEncoding` 扩展为 `FileEncoding`。同时将所有 `fs.readFileSync(path, { encoding })` 调用改为先读 Buffer 再用 `decodeBuffer` 解码，以支持 `gbk` 等非 `BufferEncoding` 编码。本 Task 依赖 Task 1（`src/utils/encoding.ts`），输出被 Task 4（写入路径适配）依赖。
-
-**涉及文件:**
-- 修改: `src/utils/fileRead.ts`
-- 修改: `src/utils/file.ts`
-- 修改: `src/utils/fileReadCache.ts`
-- 新建: `src/utils/__tests__/fileRead.test.ts`
-
-**执行步骤:**
-
-- [x] 在 `fileRead.ts` 中导入 `encoding.ts` 的类型和函数
-  - 位置: `src/utils/fileRead.ts` 文件顶部 import 区域，在 `import { getFsImplementation, safeResolvePath } from './fsOperations.js'` 之后
-  - 添加导入:
-    ```typescript
-    import { type FileEncoding, decodeBuffer, detectEncoding } from './encoding.js'
-    ```
-  - 原因: 后续步骤需要 `FileEncoding` 类型、`detectEncoding` 检测函数和 `decodeBuffer` 解码函数
-
-- [x] 改造 `detectEncodingForResolvedPath` 函数，使用 `encoding.ts` 的三层检测
-  - 位置: `src/utils/fileRead.ts` 的 `detectEncodingForResolvedPath` 函数
-  - 将函数体替换为以下逻辑:
-    ```typescript
-    export function detectEncodingForResolvedPath(
-      resolvedPath: string,
-    ): FileEncoding {
-      const { buffer, bytesRead } = getFsImplementation().readSync(resolvedPath, {
-        length: 4096,
-      })
-
-      // Empty files default to utf8 — nothing to detect
-      if (bytesRead === 0) {
-        return 'utf8'
-      }
-
-      return detectEncoding(buffer.subarray(0, bytesRead))
-    }
-    ```
-  - 关键变更:
-    - 返回类型从 `BufferEncoding` 改为 `FileEncoding`
-    - 删除内联的 BOM 检测逻辑，改为调用 `detectEncoding(buffer.subarray(0, bytesRead))`
-    - 使用 `buffer.subarray(0, bytesRead)` 截取实际读取的字节，避免尾部零字节干扰检测
-  - 原因: 将检测逻辑委托给 `encoding.ts` 的三层算法，消除代码重复
-
-- [x] 改造 `readFileSyncWithMetadata` 函数，支持非 `BufferEncoding` 解码
-  - 位置: `src/utils/fileRead.ts` 的 `readFileSyncWithMetadata` 函数
-  - 将函数签名和内部逻辑改为:
-    ```typescript
-    export function readFileSyncWithMetadata(filePath: string): {
-      content: string
-      encoding: FileEncoding
-      lineEndings: LineEndingType
-    } {

-      const { resolvedPath, isSymlink } = safeResolvePath(fs, filePath)
-
-      if (isSymlink) {
-        logForDebugging(`Reading through symlink: ${filePath} -> ${resolvedPath}`)
-      }
-
-      const encoding = detectEncodingForResolvedPath(resolvedPath)
-      // Read raw Buffer first — fs.readFileSync encoding option only accepts
-      // BufferEncoding, not gbk etc.
-      const rawBuffer = fs.readFileBytesSync(resolvedPath)
-      const raw = decodeBuffer(rawBuffer, encoding)
-      const lineEndings = detectLineEndingsForString(raw.slice(0, 4096))

-        content: raw.replaceAll('\r\n', '\n'),
-        encoding,
-        lineEndings,
-      }
-    }

-    - 返回类型中 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`
-    - `fs.readFileSync(resolvedPath, { encoding })` 改为 `fs.readFileBytesSync(resolvedPath)` 读取 Buffer
-    - 新增 `decodeBuffer(rawBuffer, encoding)` 解码为字符串
-  - 原因: `fs.readFileSync` 的 `encoding` 选项只接受 `BufferEncoding`（utf8/utf16le/latin1 等），传入 `'gbk'` 会在运行时报错
-
-- [x] 更新 `file.ts` 中 `detectFileEncoding` 的返回类型

-  - 在文件顶部 import 区域添加:
-    ```typescript
-    import { type FileEncoding, decodeBuffer, encodeString } from './encoding.js'
-    ```
-  - 原因: `detectFileEncoding` 调用 `detectEncodingForResolvedPath`，返回类型已改为 `FileEncoding`
-
-- [x] 更新 `file.ts` 中 `detectLineEndings` 的 encoding 参数类型和解码逻辑
-  - 位置: `src/utils/file.ts` 的 `detectLineEndings` 函数
-  - 将函数签名改为:
-    ```typescript
-    export function detectLineEndings(
-      filePath: string,
-      encoding: FileEncoding = 'utf8',

-  - 将内部 `buffer.toString(encoding, 0, bytesRead)` 改为:
-    ```typescript
-    const content = decodeBuffer(buffer.subarray(0, bytesRead), encoding)

-### Task 3: 异步读取路径改造
-
-**背景:**
-当前 `src/utils/readFileInRange.ts` 是 FileReadTool 的核心异步读取函数，提供 fast path（小文件整体读入）和 streaming path（大文件逐块扫描）两条路径，两者均硬编码 `encoding: 'utf8'`，导致非 UTF-8 编码文件读取乱码。本 Task 将两条路径改造为 Buffer 读取 + 编码检测 + TextDecoder 解码模式。fast path 改造简单（整体读 Buffer 后检测解码），streaming path 需要两阶段设计（先收集前 4KB 做编码检测，再用 `TextDecoder({ stream: true })` 逐 chunk 解码）。本 Task 依赖 Task 1（`src/utils/encoding.ts` 的 `detectEncoding` 和 `decodeBuffer`），输出被 Task 4 依赖（通过 `readFileInRange` 的返回值间接影响）。
-
-**涉及文件:**
-- 修改: `src/utils/readFileInRange.ts`
-- 新建: `src/utils/__tests__/readFileInRange.test.ts`
-
-**执行步骤:**
-
-- [x] 在 `readFileInRange.ts` 中导入 `encoding.ts` 的函数
-  - 位置: `src/utils/readFileInRange.ts` 文件顶部 import 区域，在 `import { formatFileSize } from './format.js'` 之后
-  - 添加导入:
-    ```typescript
-    import { detectEncoding, decodeBuffer } from './encoding.js'
-    ```
-  - 原因: fast path 和 streaming path 都需要 `detectEncoding` 做编码检测，fast path 需要 `decodeBuffer` 做一次性解码
-
-- [x] 改造 fast path — 将 `readFile` 从 UTF-8 字符串读取改为 Buffer 读取 + 检测 + 解码
-  - 位置: `src/utils/readFileInRange.ts` 的 `readFileInRange` 函数内 fast path 分支
-  - 将以下代码:
-    ```typescript
-    const text = await readFile(filePath, { encoding: 'utf8', signal })
-    return readFileInRangeFast(text, stats.mtimeMs, offset, maxLines, ...)
-    ```
-    替换为:
-    ```typescript
-    const rawBuffer = await readFile(filePath, { signal })
-    const encoding = detectEncoding(rawBuffer)
-    const text = decodeBuffer(rawBuffer, encoding)
-    return readFileInRangeFast(text, stats.mtimeMs, offset, maxLines, ...)
-    ```
-  - 关键变更: `readFile` 去掉 `encoding: 'utf8'` 选项，返回 `Buffer`；调用 `detectEncoding(rawBuffer)` 检测编码；调用 `decodeBuffer(rawBuffer, encoding)` 解码为字符串。
-  - 原因: `readFile` 的 `encoding` 选项只支持 `BufferEncoding`，不支持 `gbk` 等 ICU 编码名
-
-- [x] 改造 streaming path — 扩展 `StreamState` 类型，增加编码检测和解码相关字段
-  - 位置: `src/utils/readFileInRange.ts` 的 `StreamState` 类型定义
-  - 在现有字段之后添加以下字段:
-    ```typescript
-    type StreamState = {
-      // ... 现有字段保持不变 ...
-      /** 编码检测状态：null 表示尚未检测，string 表示已检测完成 */
-      encoding: string | null
-      /** TextDecoder 实例：检测完成后创建，用于逐 chunk 流式解码 */
-      decoder: TextDecoder | null
-      /** 检测阶段缓冲区：收集原始字节直到满 4KB 或 stream 结束 */
-      detectionBuffer: number[]
-    }
-    ```
-  - 原因: streaming 模式下 chunk 是增量到达的，需要缓冲阶段收集足够字节来调用 `detectEncoding`
-
-- [x] 改造 `streamOnData` — 处理 Buffer chunk，实现两阶段（检测阶段 + 解码阶段）
-  - 位置: `src/utils/readFileInRange.ts` 的 `streamOnData` 函数
-  - 将函数签名从 `streamOnData(this: StreamState, chunk: string): void` 改为 `streamOnData(this: StreamState, chunk: Buffer): void`
-  - 替换函数体为两阶段逻辑:
-    ```typescript
-    function streamOnData(this: StreamState, chunk: Buffer): void {
-      this.totalBytesRead += chunk.length
-
-      // ... maxBytes 检查保持不变 ...
-
-      // Phase 1: 编码检测阶段
-      if (this.encoding === null) {
-        for (let i = 0; i < chunk.length; i++) {
-          this.detectionBuffer.push(chunk[i])
-        }
-        if (this.detectionBuffer.length >= 4096) {
-          this.encoding = detectEncoding(Buffer.from(this.detectionBuffer))
-          this.decoder = new TextDecoder(this.encoding, { stream: true })
-          const decoded = this.decoder.decode(Buffer.from(this.detectionBuffer))
-          this.detectionBuffer = []
-          processTextChunk(this, decoded)
-        }
-        return
-      }
-
-      // Phase 2: 解码阶段
-      const decoded = this.decoder!.decode(chunk, { stream: true })
-      processTextChunk(this, decoded)
-    }
-    ```
-  - 原因: 两阶段设计确保编码检测在足够数据上执行（至少 4KB），检测完成后用 `TextDecoder({ stream: true })` 逐 chunk 解码
-
-- [x] 提取行扫描逻辑为独立的 `processTextChunk` 辅助函数
-  - 位置: `src/utils/readFileInRange.ts`，在 `streamOnData` 函数定义之前
-  - 从原 `streamOnData` 提取行扫描逻辑到独立函数 `processTextChunk(state: StreamState, text: string): void`
-  - 行扫描逻辑与原实现完全一致，仅变量名从 `this.` 改为 `state.`
-  - 原因: 检测阶段和解码阶段复用同一段行扫描逻辑
-
-- [x] 改造 `streamOnEnd` — 处理检测阶段缓冲区残留和最终 fragment
-  - 位置: `src/utils/readFileInRange.ts` 的 `streamOnEnd` 函数
-  - 在函数体开头插入检测阶段完成逻辑:
-    ```typescript
-    if (this.encoding === null) {
-      this.encoding = detectEncoding(Buffer.from(this.detectionBuffer))
-      this.decoder = new TextDecoder(this.encoding, { stream: true })
-      const decoded = this.decoder.decode(Buffer.from(this.detectionBuffer))
-      this.detectionBuffer = []
-      processTextChunk(this, decoded)
-    }
-    ```
-  - 原因: 小文件可能 < 4KB，stream 在检测缓冲区未满时就结束。必须在 `streamOnEnd` 中完成检测和解码
-
-- [x] 改造 `readFileInRangeStreaming` — 创建 Buffer 模式的 stream，初始化新增字段
-  - 位置: `src/utils/readFileInRange.ts` 的 `readFileInRangeStreaming` 函数
-  - 将 `createReadStream` 调用去掉 `encoding: 'utf8'` 选项
-  - 在 `state` 对象初始化中添加新字段: `encoding: null, decoder: null, detectionBuffer: []`
-  - 原因: 去掉 `encoding: 'utf8'` 后，`data` 事件回调接收 `Buffer` 对象
-
-- [x] 更新文件顶部注释，反映编码检测能力
-  - 位置: `src/utils/readFileInRange.ts` 文件顶部注释
-  - 注释已更新为: `Both paths auto-detect encoding via encoding.ts (BOM → UTF-8 fatal → fallback chain), decode with TextDecoder, and strip BOM and \r (CRLF → LF).`
-
-- [x] 为改造后的 `readFileInRange` 编写单元测试
-  - 测试文件: `src/utils/__tests__/readFileInRange.test.ts`
-  - 测试场景:
-    - **Fast path — UTF-8 文件**: 创建临时 UTF-8 文件 → 返回正确的 `content`、`lineCount`、`totalLines`
-    - **Fast path — GBK 文件**: 创建临时 GBK 编码文件 → 返回正确的中文内容（非乱码），`totalBytes` 正确
-    - **Fast path — 带行范围读取 GBK 文件**: 创建包含多行的 GBK 文件 → 返回指定行范围，内容正确
-    - **Streaming path — 大 UTF-8 文件**: 创建超过 10MB 阈值的 UTF-8 文件 → 返回正确内容
-    - **Streaming path — 大 GBK 文件**: 创建超过 10MB 阈值的 GBK 编码文件 → 返回正确的中文内容
-    - **BOM 剥离**: 创建带 UTF-8 BOM 的文件 → `content` 不包含 BOM 字符
-    - **空文件**: 创建空文件 → `content` 为空字符串，`totalLines` 为 1，`totalBytes` 为 0
-  - 运行命令: `bun test src/utils/__tests__/readFileInRange.test.ts`
-  - 预期: 所有测试通过
-
-**检查步骤:**
-
-- [x] 验证 `readFileInRange.ts` 已导入 `encoding.ts` 的函数
-  - `grep -n "detectEncoding\|decodeBuffer" src/utils/readFileInRange.ts`
-  - 预期: import 行包含 `detectEncoding` 和 `decodeBuffer`，函数体中包含调用
-
-- [x] 验证 streaming path 不再硬编码 `encoding: 'utf8'`
-  - `grep -n "encoding: 'utf8'\|encoding: \"utf8\"" src/utils/readFileInRange.ts`
-  - 预期: 无匹配结果

-- [x] 验证 `createReadStream` 调用无 encoding 选项
-  - `grep -A3 "createReadStream" src/utils/readFileInRange.ts`

-- [x] 验证 `StreamState` 类型包含编码检测新字段
-  - `grep -n "encoding:\|decoder:\|detectionBuffer:" src/utils/readFileInRange.ts`
-  - 预期: `StreamState` 类型定义中包含 `encoding`、`decoder`、`detectionBuffer` 字段
-
-- [x] 验证 `processTextChunk` 函数存在
-  - `grep -n "function processTextChunk" src/utils/readFileInRange.ts`
-  - 预期: 函数定义存在
-
-- [x] 运行 readFileInRange 单元测试
-  - `bun test src/utils/__tests__/readFileInRange.test.ts`
-  - 预期: 所有测试通过
-
-- [x] 运行 precheck 确认无类型/lint/测试错误
-  - `bun run precheck`
-  - 预期: 零错误通过
-
-**认知变更:**
-- [x] [CLAUDE.md] `readFileInRange.ts` 的 streaming path 使用两阶段编码检测：先收集前 4KB 字节调用 `detectEncoding`，再用 `TextDecoder({ stream: true })` 逐 chunk 流式解码。`TextDecoder` 的 `{ stream: true }` 模式会自动处理多字节字符跨 chunk 边界问题。对于 < 4KB 的小文件，检测在 `streamOnEnd` 中完成。

-### Task 4: 写入路径和工具层适配
-
-**背景:**
-[业务语境] — 当用户通过 FileEditTool 或 FileWriteTool 编辑非 UTF-8 编码文件（如 GBK）时，写入操作需要将内部 UTF-8 字符串编码回原文件编码，否则写入的内容会乱码。当前 `writeTextContent` 只接受 `BufferEncoding` 类型，无法处理 gbk 等编码。
-[修改原因] — `writeTextContent` 的 `encoding` 参数类型为 `BufferEncoding`，`writeFileSyncAndFlush_DEPRECATED` 内部直接将 encoding 传给 `fs.writeFileSync`（只接受标准 BufferEncoding）。`FileEditTool.validateInput` 中硬编码了 BOM-only 编码检测，无法识别 GBK 文件。
-[上下游影响] — 本 Task 依赖 Task 1 创建的 `encodeString` 函数和 `FileEncoding` 类型。`FileEditTool` 和 `FileWriteTool` 通过 `writeTextContent` 间接依赖本 Task 的改造。BashTool 和 NotebookEditTool 也调用 `writeTextContent`，签名变更后它们无需额外改动（encoding 参数类型由上游传入，自动兼容）。
-
-**涉及文件:**
-- 修改: `src/utils/file.ts`
-- 修改: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts`
-
-**执行步骤:**
-
-- [x] 在 `src/utils/file.ts` 中合并 `encodeString` 到 Task 2 已创建的 `encoding.js` 导入
-  - 位置: 文件导入区域，Task 2 已添加的 `import { type FileEncoding, decodeBuffer } from './encoding.js'` 行
-  - 将该行改为: `import { type FileEncoding, decodeBuffer, encodeString } from './encoding.js'`
-  - 原因: 避免对同一模块创建两个 import 语句
-
-- [x] 将 `writeTextContent` 的 `encoding` 参数类型从 `BufferEncoding` 改为 `FileEncoding`
-  - 位置: `src/utils/file.ts:writeTextContent()`
-  - 修改函数签名:
-    ```typescript
-    export function writeTextContent(
-      filePath: string,
-      content: string,
-      encoding: FileEncoding,
-      endings: LineEndingType,
-    ): void
-    ```
-  - 修改函数体，在行尾处理之后、调用 `writeFileSyncAndFlush_DEPRECATED` 之前，增加编码判断逻辑:
-    ```typescript
-    const BUFFER_ENCODINGS = new Set<string>([
-      'utf8', 'utf-8', 'utf16le', 'ucs2', 'ucs-2',
-      'ascii', 'latin1', 'binary', 'base64', 'hex',
-    ])
-
-    if (BUFFER_ENCODINGS.has(encoding)) {
-      writeFileSyncAndFlush_DEPRECATED(filePath, toWrite, { encoding: encoding as BufferEncoding })
-    } else {
-      // 非 BufferEncoding（如 gbk），使用 encodeString 获取 Buffer
-      const { buffer, converted } = encodeString(toWrite, encoding)
-      writeFileSyncAndFlush_DEPRECATED(filePath, buffer, { buffer })
-      if (converted) {
-        logForDebugging(
-          `writeTextContent: encoding '${encoding}' unsupported for write, fell back to UTF-8 for ${filePath}`,
-          { level: 'warn' },
-        )
-      }
-    }
-    ```
-  - 原因: `fs.writeFileSync` 只接受标准 BufferEncoding，对于 gbk 等编码必须先转为 Buffer 再写入
-
-- [x] 扩展 `writeFileSyncAndFlush_DEPRECATED` 支持 Buffer 写入
-  - 位置: `src/utils/file.ts:writeFileSyncAndFlush_DEPRECATED()`
-  - 修改函数签名中 `content` 参数类型和 `options` 类型:
-    ```typescript
-    export function writeFileSyncAndFlush_DEPRECATED(
-      filePath: string,
-      content: string | Buffer,
-      options: { encoding?: BufferEncoding; mode?: number; buffer?: Buffer } = {},
-    ): void
-    ```
-  - 修改原子写入路径的 `writeOptions` 构建逻辑:
-    ```typescript
-    const isBufferWrite = Buffer.isBuffer(content) || options.buffer !== undefined
-    const writeData = options.buffer ?? content
-    const writeOptions: {
-      encoding?: BufferEncoding
-      flush: boolean
-      mode?: number
-    } = {
-      flush: true,
-      ...(isBufferWrite ? {} : { encoding: options.encoding ?? 'utf-8' }),
-    }
-    ```
-  - 修改非原子回退路径，使用相同的 `isBufferWrite` / `writeData` / `writeOptions` 模式
-  - 原因: `fs.writeFileSync(path, buffer)` 可以直接写入 Buffer，不需要 encoding 参数
-
-- [x] 在 `FileEditTool.ts` 中导入 `FileEncoding` 和 `detectEncoding` / `decodeBuffer`
-  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts` 导入区域
-  - 添加: `import { detectEncoding, decodeBuffer, type FileEncoding } from 'src/utils/encoding.js'`
-  - 原因: `validateInput` 编码检测和 `readFileForEdit` 返回类型需要 `FileEncoding` 类型
-
-- [x] 将 `readFileForEdit` 返回类型中的 `encoding` 从 `BufferEncoding` 改为 `FileEncoding`
-  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts:readFileForEdit()`
-  - 修改返回类型声明:
-    ```typescript
-    function readFileForEdit(absoluteFilePath: string): {
-      content: string
-      fileExists: boolean
-      encoding: FileEncoding
-      lineEndings: LineEndingType
-    }
-    ```
-  - 原因: `readFileSyncWithMetadata` 返回的 `encoding` 类型已由 Task 2 改为 `FileEncoding`
-
-- [x] 改造 `FileEditTool.validateInput` 中的编码检测逻辑
-  - 位置: `packages/builtin-tools/src/tools/FileEditTool/FileEditTool.ts:validateInput()`
-  - 将现有的 BOM-only 编码检测:
-    ```typescript
-    const encoding: BufferEncoding =
-      fileBuffer.length >= 2 && fileBuffer[0] === 0xff && fileBuffer[1] === 0xfe
-        ? 'utf16le'
-        : 'utf8'
-    fileContent = fileBuffer.toString(encoding).replaceAll('\r\n', '\n')
-    ```
-  - 替换为:
-    ```typescript
-    const encoding: FileEncoding = detectEncoding(fileBuffer)
-    fileContent = decodeBuffer(fileBuffer, encoding).replaceAll('\r\n', '\n')
-    ```
-  - 原因: 使 validateInput 也能正确识别 GBK 文件，避免编辑时因编码检测不一致导致 old_string 匹配失败
-
-- [x] 为 `writeTextContent` 的多编码写入能力编写单元测试
-  - 测试文件: `src/utils/__tests__/file.test.ts`
-  - 在现有测试 describe 块之后追加新的 describe('writeTextContent with multi-encoding') 块
-  - 测试场景:
-    - UTF-8 写入: 写入 UTF-8 内容 → 文件内容正确，无回退警告
-    - UTF-16LE 写入: 写入 UTF-16LE 内容（含 BOM） → 文件二进制内容与预期一致
-    - GBK 写入回退: 对 gbk 编码调用 `writeTextContent` → 文件以 UTF-8 写入（`encodeString` 回退行为），内容不损坏
-    - CRLF 行尾 + GBK: `endings: 'CRLF'` + gbk 编码 → 行尾正确转换为 `\r\n`，编码回退为 UTF-8
-  - 注意: 需要 mock `src/utils/debug.ts`（使用共享 mock `tests/mocks/debug.ts`）
-  - 运行命令: `bun test src/utils/__tests__/file.test.ts`
-  - 预期: 所有测试通过
-
-**检查步骤:**
-- [x] 验证 `writeTextContent` 签名使用 `FileEncoding` 类型
-  - `grep -n 'encoding: FileEncoding' src/utils/file.ts`
-  - 预期: 输出包含 `writeTextContent` 函数定义行
-
-- [x] 验证 `writeFileSyncAndFlush_DEPRECATED` 支持 Buffer 写入
-  - `grep -n 'content: string | Buffer' src/utils/file.ts`

-  - 预期: 输出包含 `readFileForEdit` 函数的返回类型声明
