Two faults found by watching it run. The heartbeat was the only cadence,
so the first pass ran before mDNS discovery finished, saw nothing, and
then sat silent for two minutes - precisely when someone has just
switched the relay on and is watching for it to work. It now polls every
five seconds until the first successful report, then settles.
And nothing restarted the service after a reboot or an app update, which
is the most common way it dies during development. A relay that has
quietly stopped is worse than one never switched on: the endpoint it last
published keeps looking authoritative while pointing at a port nothing is
listening on. RelayBootReceiver handles BOOT_COMPLETED and
MY_PACKAGE_REPLACED, debug builds only, and does nothing unless the relay
was already on.
Verified end to end: installing this build triggered the receiver and the
phone reported its endpoint 7 seconds later, unattended.
