This commit addresses several issues related to playback state reporting and metadata handling:
1. In the backend (pmocontrol), the music renderer now correctly uses raw playback states instead of computed logical states for event emission, and fixes stream time calculation to only occur when the device is actually playing.
2. The frontend (CurrentTrack.vue) now logs additional debug information for duration and transport state to help trace playback issues.
3. The SSE event handling in useRenderers.ts has been enhanced with more detailed logging and uses deep copying to prevent shared state issues between renderers.
4. The OpenHome queue implementation now uses a Mutex for metadata caching and implements logic to prevent duration from decreasing for the same track, which helps stabilize metadata for streaming content.
These changes improve the reliability and accuracy of playback state and metadata display across all components.
