The box is offline and being reconfigured. Removed the relay helper URL from
.env (qwen_tts_helper_url defaults to empty, so local :8881 is now the only
backend), dropped the 18881 relay entry from MEANINGFUL_PORTS, and made the
node report state plainly that no controller endpoint exists rather than
advertising one on a retired host.
Also recorded that ModelCoordinator.ensure_qwen_server() already spawns the
Qwen server on demand - it checks /health first, so a launchd-owned instance is
reused instead of double-spawned.
