Fix TUI: show GyanDoot banner + wire live agent responses

Browse Source 
Two bugs fixed:

1. Banner not shown: TUI default output was a plain welcome text
   instead of the actual GyanDoot banner. Fixed by using
   banner::banner_plain() as initial TUI output content.

2. No agent responses: TUI was a standalone shell with no connection
   to the agent loop. Now uses mpsc channels:
   - user_tx: TUI → agent (user sends messages)
   - event_rx: agent → TUI (agent sends responses + telemetry)
   - TuiEvent::Response / Status / Telemetry enum for structured
     communication
   - tokio::spawn runs agent in background processing messages
   - poll_events() in render loop drains channel every frame tick

Also updated cmd_tui() in main to create channels + spawn agent.
