Off (default): SIGKILL the daemon on addon stop so the UPS keeps power
on. On: SIGTERM it (native behavior) so it saves the RTC and tells the
UPS to cut power. Add translations so the option is documented in the
HA config UI, and document the difference in the README.

The daemon treats SIGTERM as system shutdown and clears PI_RUNNING,
making the UPS cut power seconds after the addon stops. Trap the stop
signal and SIGKILL the daemon instead so the UPS is never notified.
When the daemon exits on its own because the UPS commanded a shutdown
(button, low battery, auto shutdown), its init-0 trigger is useless in
a container, so run.sh now performs a clean host shutdown through the
Supervisor (requires hassio admin role).

VOUT_MAX is the safety limit above which the UPS refuses to boot an
externally-powered Pi, not an output voltage setting. Also clarify
PI_RUNNING, WATCHDOG_GRACE and TOUCH_STATE names, and add documented
units: timeouts and watchdog values are CLI-scaled seconds,
AUTO_SHDN_TIME is minutes; SHDN_DELAY stays raw ticks.

The latest homeassistant base images use s6-overlay v3, whose /init
refuses to run unless it is PID 1. Set init:false so the Supervisor does
not inject docker-init in front of it.

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.
