feat: 新增 6 个工具并重组目录结构
新增工具: - grep_content: 在文件内容中搜索文本/正则表达式 - get_file_info: 获取文件元信息(大小、权限、时间等) - move_file: 移动或重命名文件/目录 - copy_file: 复制文件或目录(支持递归) - delete_file: 删除文件或目录 - create_directory: 创建目录 目录重组: - src/tools/shell/ - Shell 相关工具(bash) - src/tools/filesystem/ - 文件系统工具(12个) - 每个子目录有独立的 index.ts 导出 权限系统扩展: - 新增操作类型: grep, info, move, copy, mkdir - 读取类操作默认允许,写入类操作需要确认
