v1.1.1's route observer re-forced speaker on every change, and WebKit re-added Bluetooth
each time -> the audio flapped speaker<->BT many times/sec (telemetry: dozens of route
flips from 3 taps), which read as 'sound doesn't switch'. WKWebView won't let the app
hold the built-in speaker over an active BT device. So: one override per tap, observer
only REPORTS the output (no fighting). Also stop dimming the iOS button (it's a live
output indicator, not on/off; the dim read as 'disabled' on BT). Probe now carries the
native marker so we can confirm the binary. plugin v1.1.2-stable, web batch150.
