Frontend:
- Fix term.onData to use wsRef.current instead of captured ws variable
- Fix fitTerminal to use wsRef.current for resize messages
- Fix sendData callback to use wsRef.current
- This fixes 'cannot type' after WebSocket reconnect
Backend:
- Add SessionRef class for mutable session reference
- Update _read_loop and _write_loop to use SessionRef
- Reset now updates session_ref.session instead of returning
- This keeps the WebSocket alive after reset instead of closing it
