refactor(core): 移除 get_file_info 和 list_directory 工具

这些工具功能可通过 bash 命令 (ls, stat, file) 实现，不再需要单独的工具。

删除的文件:
- src/tools/filesystem/get_file_info.ts
- src/tools/filesystem/list_directory.ts
- src/tools/descriptions/filesystem/get_file_info.txt
- src/tools/descriptions/filesystem/list_directory.txt
- tests/unit/tools/filesystem/get_file_info.test.ts
- tests/unit/tools/filesystem/list_directory.test.ts

更新的文件:
- src/tools/index.ts: 移除导入和注册
- src/tools/filesystem/index.ts: 移除导出
- src/tools/load_description.ts: 移除映射
- src/agent/presets/*.ts: 移除 tools.enabled 引用
- tests/unit/tools/load_description.test.ts: 移除测试数据
