Function spawn_web 

pub async fn spawn_web(
    ui_state: Arc<Mutex<UiState>>,
    broadcast_tx: Sender<WsMessage>,
    config: WebConfig,
) -> (SocketAddr, Receiver<String>)

Spawn the web server on a Tokio task.

Returns the bound address and a receiver for chat messages sent from the browser (via POST /api/chat or {"type":"chat"} WebSocket messages). Read from the receiver in your agent loop to drive conversation turns.

The server runs until the Tokio runtime shuts down.

Arguments

• ui_state — Shared agent state (same instance passed to UiEventHandler).
• broadcast_tx — Sender half of the WebSocket broadcast channel. Pass the same sender to WebBroadcastHandler::new().
• config — Server configuration.
