The AppDelegate codemod no longer configures AVAudioSession at boot (previously .playAndRecord + .allowBluetooth only, i.e. no A2DP, fixed for the app's lifetime). AUAudioUnitRTCAudioDevice now owns the session via an AudioSessionCoordinator that derives category/mode/options from playback vs recording state, so Bluetooth headphones get full-quality A2DP routing during playback and the device recovers from route changes and media services resets instead of requiring an app restart. Also drops the enableStereoOutput line from the ObjC codemod variant: this fork's WebRTCModuleOptions has no such property, so that path could never have compiled.
