refactor(core): 实现类型安全的工具定义系统

- 新增 defineTool 函数，使用 Zod schema 定义参数并自动推断 TypeScript 类型
- 重构文件系统工具 (read_file, write_file, edit_file, glob, grep, multi_edit) 使用 Zod 类型推断
- 重构 shell 工具 (bash, kill_shell) 使用新的类型安全系统
- 重构 task 工具 (task, task_output) 使用 Zod 验证
- 兼容 Zod v4 API (处理 _zod.def vs _def, error.issues vs error.errors)
- 导出参数类型供外部使用 (ReadFileParams, BashParams 等)
- 统一参数命名: path -> file_path
- 修复相关测试以适配新的参数结构和输出格式
- 移除不存在工具的测试文件
