Runs as a host-level systemd timer on CT122 (scripts/discover-devices.sh) rather than inside the api container, since real ARP entries live in the host's network namespace, not Docker's bridge network. See docs/device-discovery.md for the full writeup, including why literal passive-only ARP reading was dropped (near-empty result in practice). API reads the resulting JSON file each poll cycle, cross-references config/hosts.yaml's knownDevices list by IP, and serves /api/devices. Dashboard gets a new "Network Devices" table. Closes #9.
