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。 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * 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/） Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * 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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * 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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: 修复 node 环境没有 bun 的问题 --------- Co-authored-by: Eric-Guo <eric.guocz@gmail.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
