- Introduced `pytest-benchmark` dependency for performance testing of critical code paths.
- Added a new `PartialAudioBuffer` class to optimize audio chunk handling, reducing memory allocations and improving efficiency.
- Implemented benchmark tests for audio processing, validating performance improvements and establishing baselines.
- Enhanced the `Segmenter` class to utilize cached sample counts for faster duration calculations.
- Updated gRPC service to leverage consolidated streaming state, reducing multiple dictionary lookups to a single access.
All quality checks pass.
