feat: 工具层及 mcp 大重构 (#252)

* feat: 第一版大重构

* fix: 修复类型问题

* chore: 更新版本到 1.3.2

* Add brave as alternative WebSearchTool

* fix: 修正顺序

* fix: 修复对穷鬼模式的 auto dream 和 session memory 越过

* feat: 穷鬼模式去除 session-summary

* feat: 创建 builtin-tools 包，搬运所有工具实现

将 src/tools/ 下的全部 60 个工具目录迁移至 packages/builtin-tools/src/tools/，
内部导入路径已更新为 src/ alias 模式。

* refactor: 更新 src/ 中所有工具引用至 builtin-tools 包，删除 src/tools/

- src/tools.ts 及 178 个 src/ 文件的 import 路径从 ./tools/ 改为 builtin-tools/tools/
- 删除 src/tools/ 整个目录（已迁移至 packages/builtin-tools/）

* chore: 添加 builtin-tools 路径别名至 tsconfig，更新 bun.lock

- tsconfig.json 新增 builtin-tools/* 和 builtin-tools 路径映射
- 新增 packages/builtin-tools/src 至 include

* refactor: 为 builtin-tools、mcp-client、agent-tools 添加 @claude-code-best 作用域前缀

所有包名及 import 路径统一添加 @claude-code-best/ 前缀：
- builtin-tools → @claude-code-best/builtin-tools
- mcp-client → @claude-code-best/mcp-client
- agent-tools → @claude-code-best/agent-tools
