feat: implement audio object definitions and refactor audio system

- Add AudioObjectDefinitions.cs with name-to-ID mappings and ambiguity detection - Update AudioSystem.cs to support Play(uint) and deprecated Play(string) with warnings - Rename PitchStepManager to PitchStepResolver and update all references - Refactor generated code to use 'this.' prefix and foreach loops - Remove TestEnum from audio enums and IDs - Update SampleScene.unity to use new AudioSystem namespace and rain sound parameter - Optimize binary serialization in generated audio classes
