- Add VfsFile: Send supertrait for Mutex compatibility - Fix SmbServerCommand: struct → Subcommand enum with Start variant - Fix tracing_subscriber::init() → try_init() to avoid panic when logger already initialized - Fix CLI subcommand name: smb-server → smb-start (flatten naming) - Add #[command(name = "smb-start")] for CLI disambiguation - Fix unused variable warnings (smb_fs.rs, smb_server_backend.rs) - Remove unused VfsFile imports (webdav.rs, scp_handler.rs) - Integration test: Docker smbclient verified (list, upload, read)
