Wire heartbeat into NexusMind consciousness loop

The heartbeat module existed but was never called. Now write_heartbeat fires:
- On startup (cycle 0, status thinking)
- After every successful think cycle
- On graceful shutdown (status idle)

This gives the watchdog a signal that the mind is alive, not just running.
