Phase 3完成：FUSE完整重构以支持fuse-t
核心成果： - fuse-t库成功纳入项目（build.rs + Cargo.toml） - fuse-backend-rs API完整实现（270行代码） - FileSystem trait完整重写（lookup/getattr/read/readdir/open/release/opendir/releasedir/statfs） - ZeroCopyWriter API正确集成（write_from方法） - 服务循环正确实现（get_request + handle_message） 技术实现： - 依赖：fuse-backend-rs（fusedev + fuse-t features） - 链接：fuse-t库（pkg-config + DiskArbitration framework） - 数据库：find_node_id_by_parent方法新增 - API：DirEntry/Entry/stat64正确使用 - 服务：FuseSession/FuseChannel正确集成 编译状态： - 8警告，0错误 - 成功编译markbase-fuse库和main程序 状态：Phase 3完整实施完成
