Replace WAV with Opus encoding for Whisper API uploads: - Add libopus & libogg via FetchContent (no vcpkg dependency) - Implement AudioBuffer::saveToOpus() with Ogg container - Configure Opus encoder for voice (VOIP mode, 32kbps VBR) - Update WhisperClient to use Opus format (audio/ogg) - Fix Windows temp file path compatibility Benefits: - 46x smaller files (37KB vs 1.7MB for 10s audio) - Reduced API costs and bandwidth - Faster uploads for real-time translation - Whisper API fully supports Opus/Ogg format 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
