The Desktop App and Web Dashboard remote-connect instructions told users
to start the backend with `hermes dashboard --no-open --insecure --host
0.0.0.0`, omitting --tui. Without --tui the embedded-chat WebSockets
(/api/ws, /api/pty) are refused, so the desktop passes the /api/status
health check and reports the backend "ready" — but chat never works
because the socket is closed on connect.
- Add --tui to both backend command blocks (with an inline why-comment).
- Explain that the desktop chat runs over /api/ws + /api/pty and needs
the embedded-chat surface enabled; a plain dashboard/gateway is not
enough.
- Add a troubleshooting entry for the exact symptom (connects, says
ready, chat dead) on both pages.
