Rework the MQTT bridge into a single deployable unit: - Drop the self-SSH hop; run locally on steel141 (on the TV's LAN, has bscpylgtv, effectively always-on). - Cache last-known TV IP and probe it directly; /24 ping-sweep only on a cache miss. Stops the 30s HA state poll from flapping/spamming the net. - WoL now unicast (last-known IP) + broadcast, ports 9/7, 3 bursts. - systemd unit (User=seth, EnvironmentFile for MQTT_PASSWORD), install.sh, env template, .gitignore. Removes the half-finished lgtv.sh.new. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
