The daemon must contact the UPS within PI_BOOT_TO seconds of power-on
or the UPS cuts power. Start it immediately via exec as the container's
main process; run the MQTT monitor in a background loop with 30s restart
backoff so Supervisor API delays or monitor crashes can never delay or
kill the daemon.

Poll lifepo4wered-cli every 30s (configurable), publish all registers as
one JSON state payload, and announce sensors/binary sensor via MQTT
discovery. run.sh pulls broker credentials from the Supervisor mqtt
service (Mosquitto addon) with manual overrides in addon options.
