Telemetry proof: overrideOutputAudioPort(.none) routes to Receiver once, then every
later toggle latches to built-in Speaker despite opts=36 (no .defaultToSpeaker) —
WebKit's WebRTC engine re-forces the loudspeaker after our override. The prior build
ignored .override-reason route changes and never corrected it.
Now: react to ALL route changes, debounced 0.25s, and re-assert the chosen port only
on a genuine mismatch (self-terminating, capped at 6/toggle to avoid thrash). setSpeaker
returns a reason->port route-change trail so the log shows whether WebKit is one-shot
or persistent. native marker 1.0.3-reassert.

Telemetry only showed 'override didn't throw', and the web __BUILD tag can't tell
native binaries apart, so we couldn't see WHERE iOS actually routed the audio or
which plugin build ran. setSpeaker now resolves with the real currentRoute output
port (Receiver/Speaker/Bluetooth), the live AVAudioSession category/mode/options,
and a native-build marker (1.0.2-diag) so the route log is unambiguous.

Speaker worked but the earpiece was silent, and call audio flickered on speaker
then dropped. Causes: (1) the category set .defaultToSpeaker, so overrideOutputAudioPort(.none)
fell back to the loudspeaker instead of the receiver; (2) setSpeaker re-ran
setCategory+setActive on every toggle mid-call, tearing down the audio unit WebKit's
WebRTC engine was using and silencing the earpiece route.
Fix: drop .defaultToSpeaker (drive the port explicitly), make setSpeaker flip ONLY
overrideOutputAudioPort, and observe routeChangeNotification to re-assert the chosen
route when WebKit reconfigures the session at call start / device change.

Device telemetry proved the app-embedded AudioRoute class never registered (not in
Capacitor.Plugins) — appending a CAPBridgedPlugin to AppDelegate.swift gets stripped/undiscovered
in release builds. The plugins that DO register (Share, Camera, Filesystem) are all npm packages
wired by cap sync. So AudioRoute is now a local plugin package (mobile/plugins/audio-route,
file: dep in mobile/package.json) with a podspec + CAPBridgedPlugin Swift — cap sync adds its pod
and Capacitor registers it like the others. load() sets the launch speaker default; setSpeaker({on})
overrides the output port. inject-audio.js no longer injects the plugin class (would duplicate);
it keeps only the AppDelegate launch default as a fallback.
