Introduce WebSocket-based remote session relay so external clients can
subscribe to sessions, send messages, answer questions, and respond to
permissions in real time.
- RemoteWS manages the authenticated WebSocket lifecycle with reconnect
- RemoteSender dispatches inbound commands and forwards server events
- Backfill pending questions/permissions when a client subscribes
- Add question_reject command for dismissing questions remotely
- Consolidate /remote TUI command into kilo-commands
- Add session.viewed endpoint to the generated SDK
- RemoteProtocol.Preview schema for diagnostic logging
