Add daemon restart feature from settings (#18)

* Add daemon restart feature from settings

This adds the ability to restart a connected daemon from the settings page.
The feature includes:

- Backend: RestartDaemon command added to DaemonCommand enum
- Backend: New POST /api/v1/mesh/daemons/{id}/restart endpoint
- Backend: Daemon gracefully shuts down tasks and exits with code 42
  (can be used by process managers like systemd to detect restart requests)
- Frontend: restartDaemon() API function
- Frontend: Restart button in Connected Daemons section of settings
- Frontend: Confirmation dialog before restart to prevent accidental restarts

When a daemon receives the restart command, it:
1. Gracefully shuts down all running Claude processes (5s timeout)
2. Exits with code 42 to signal restart requested
3. The daemon can be restarted by a process manager or manually
