NsdManager service discovery needs NEARBY_WIFI_DEVICES on Android 13+. The app DECLARED it but
never REQUESTED it, so on a real device the permission stayed denied and discoverServices silently
found nothing — no prompt, no hosts. (It only worked on the emulator because the permission was
granted via `adb pm grant`.) Request it (mirroring the mic RECORD_AUDIO flow) when the connect
screen appears, and start/restart discovery once granted; on API < 33 discovery starts immediately
(the permission doesn't apply there). The advertised hosts the Apple clients already see will then
appear here too.
