Refactor ASR plugin options and improve audio processing

- Renamed `hideTimeout` to `autoHideTimeout` for clarity.
- Updated the default options destructuring for better readability.
- Removed unnecessary comments and cleaned up the audio processing logic.
- Ensured that the audio buffer is processed correctly before sending to the `onAudioChunk` callback.
