Pull request overview
Adds an opt-in “tunnel host” capability so the Sessions desktop app can expose a local agent host over a dev tunnel (enabling remote connections), including a UI toggle and shared-process hosting implementation.
Changes:
- Add Sessions desktop contribution + UI action/view-item to toggle “Allow Remote Connections” and view related output.
- Introduce a renderer-side
ITunnelHostServicethat requests an on-demand local agent-host WebSocket listener and starts/stops hosting via shared process IPC. - Add a shared-process
TunnelHostMainServicethat creates/dev-hosts a dev tunnel and pipes forwarded connections into the local agent host socket.
