feat(appd): add weft-appd skeleton crate and service unit New crate implementing the application daemon entry point: - crates/weft-appd/Cargo.toml: tokio (current-thread runtime), anyhow, sd-notify, tracing dependencies - crates/weft-appd/src/main.rs: async run() resolves IPC socket path from WEFT_APPD_SOCKET or XDG_RUNTIME_DIR/weft/appd.sock; stubs for AppRegistry, IpcServer, CompositorClient, RuntimeSupervisor, CapabilityBroker, ResourceController per WEFT-OS-APPD-DESIGN.md; sd_notify(READY=1) to be sent after IpcServer bind + CompositorClient connect - infra/systemd/weft-appd.service: Type=notify, Requires+After weft-compositor.service, After servo-shell.service Also fix two winit backend issues that were present in the working tree: - remove spurious mut on display binding (never mutated after init) - wrap std::env::set_var in unsafe block (required since Rust 1.80)

feat(appd): implement IPC server with Unix socket and MessagePack framing Replaces the skeleton bail with a functional IPC server. ipc.rs — transport layer: - Request enum: LaunchApp, TerminateApp, QueryRunning, QueryAppState. Serialized with serde MessagePack (rmp-serde, SCREAMING_SNAKE_CASE type tag). - Response enum: LaunchAck, AppReady, RunningApps, AppState, Error. - AppStateKind: Starting, Running, Stopping, Stopped, NotFound. - read_frame / write_frame: async 4-byte LE length-prefixed codec over any AsyncRead / AsyncWrite. main.rs — server: - SessionRegistry: in-memory HashMap<session_id, AppStateKind> with monotonic ID counter; launch / terminate / running_ids / state. - run(): creates socket parent directory, removes stale socket, binds UnixListener, sends sd_notify READY=1, then accept-loops with ctrl-c / SIGTERM shutdown. Cleans up socket on exit. - handle_connection(): splits stream into BufReader/BufWriter, reads request frames, calls dispatch, writes response frames. - dispatch(): maps Request variants to SessionRegistry operations; returns typed Response. Wasmtime spawning and compositor client deferred to later implementation. New deps: serde (derive), rmp-serde, tokio net/io-util/sync/rt-multi-thread.

feat(appd): add WebSocket UI endpoint for Servo shell integration Implements the weft-appd WebSocket server that allows the system-ui.html page running inside Servo to send requests and receive push notifications without requiring custom SpiderMonkey bindings. ws.rs — WebSocket connection handler: - Accepts a tokio TcpStream, performs WebSocket handshake via tokio-tungstenite accept_async. - Reads JSON Text frames, deserializes as Request (serde_json), calls dispatch(), sends Response as JSON Text. - Subscribes to a broadcast::Receiver<Response> for server-push notifications (APP_READY, etc.); forwards to client via select!. - Handles close frames, partial errors, and lagged broadcast gracefully. main.rs — server changes: - broadcast::channel(16) created at startup; WebSocket handlers subscribe for push delivery. - TcpListener bound on 127.0.0.1:7410 (default) or WEFT_APPD_WS_PORT. - ws_port() / write_ws_port(): port written to XDG_RUNTIME_DIR/weft/appd.wsport for runtime discovery. - WS accept branch added to the main select! loop alongside Unix socket. ipc.rs — Response and AppStateKind now derive Clone (required by broadcast::Sender<Response>). system-ui.html — appd WebSocket client: - appdConnect(): opens ws://127.0.0.1:<port>/appd with exponential backoff reconnect (1s → 16s max). - On open: sends QUERY_RUNNING to populate taskbar with live sessions. - handleAppdMessage(): maps LAUNCH_ACK and RUNNING_APPS to taskbar entries; APP_READY shows a timed notification; APP_STATE::stopped removes the taskbar entry. - WEFT_APPD_WS_PORT window global overrides the default port. New deps: tokio-tungstenite 0.24, futures-util 0.3 (sink+std), serde_json 1.
