[devopvoid]

• 86 JNI entry points that convert or allocate now catch C++ exceptions instead of letting them abort the VM.
• Pinned byte arrays are null-checked and released through RAII in the audio and video buffer natives; AudioProcessing no longer leaks them on its early return.
• AudioProcessing.processStream/processReverseStream return kBadDataLengthError for arrays shorter than the frame instead of reading and writing past them.
