Pull request overview
This pull request improves robustness of audio loading from in-memory buffers by adding a minimum-size guard in the core audio buffer loader, and adds a C API regression test to ensure undersized/malformed buffers are rejected with a clear error instead of crashing.
Changes:
- Add a minimum audio buffer size check in
LoadAudiosFromBuffersto reject trivially undersized inputs early. - Add a C API regression test that passes an undersized malformed buffer and asserts an error is returned (and no
OgaAudiosis produced).

This pull request improves the robustness of audio buffer handling by adding a minimum size check for audio data and introduces a regression test to ensure malformed buffers are properly rejected. These changes prevent crashes due to undersized or malformed audio buffers and improve error reporting. **Audio buffer validation:** * Added a minimum buffer size check (`kMinAudioBufferSize = 44`) in `LoadAudiosFromBuffers` to reject audio buffers that are too small to contain a valid audio header, throwing a clear runtime error if violated. **Testing improvements:** * Added a regression test (`LoadAudiosFromBuffersRejectsTooSmallBuffer`) to ensure that audio buffers smaller than the minimum required size are rejected with a descriptive error, preventing heap-buffer-overflow crashes. Onnxruntime-extensions validation check: microsoft/onnxruntime-extensions#1079
