FSKit简化版成功：编译通过 + Tests passing
关键决策： - 放弃 objc2::declare_class（编译失败） - 采用纯 Rust struct（编译成功） - SQLite backend完整整合 Tests结果： - test_markbase_fs_creation ✅ - test_file_node_data ✅ - test_volume_creation ✅ - 3/3 passing 功能实现： - MarkBaseFS: query_node + query_children + read_file - MarkBaseVolume: find_root_node + statfs - Binary: fskit_mount (3.4MB) + fskit_poc (3.4MB) 下一步： - warren.sqlite 数据验证 - System Extension 注册研究
