MethodChannelSystemAudioMeter class

An implementation of SystemAudioMeterPlatform that uses method channels.

This class is the default runtime backend used by Flutter code. Forks that add new desktop platforms can use it as a reference for channel naming, payload shapes, and Dart-side parsing conventions.
