feat(darwin): run Frigate ANE object detector as a launchd agent on dungeon#63

Conversation
…ungeon Add launchd.user.agents.frigate-detector running the native frigate-nvr/apple-silicon-detector, so Frigate (inside OrbStack's Linux VM, which can't reach the ANE) can offload object detection to the Apple Neural Engine over ZMQ/TCP. Mirrors the existing native-exporter agent pattern. Document the one-time clone + venv install in darwin-post-deploy.md (the repo is not auto-cloned).

Why
Frigate's CPU object detector was the single biggest CPU consumer on dungeon (~64% of a ~130% total).
Frigate runs inside OrbStack's Linux VM, which can't reach the Apple Neural Engine, so the detector
has to run natively on the Mac and Frigate connects to it over ZMQ/TCP. (Companion change in the
home-lab repo points Frigate at it.)
What
launchd.user.agents.frigate-detectortonixos/hosts/macs/dungeon/default.nix, running thenative
frigate-nvr/apple-silicon-detector(
venv/bin/python3 detector/zmq_onnx_client.py, defaults totcp://*:5555,--model AUTO). Mirrorsthe existing native-exporter agent pattern (node_exporter / macmon / glances):
RunAtLoad,KeepAlive, logs to~/Library/Logs/frigate-detector.log.nixos/docs/darwin-post-deploy.md(the detector repois not auto-cloned).
Deploy
The detector repo + venv must exist first (see the post-deploy checklist), then
darwin-rebuild switchstarts the agent. Verify withtail ~/Library/Logs/frigate-detector.log→ "ZMQ server successfully bound to tcp://*:5555".🤖 Generated with Claude Code
