Bump version to 0.3.20 and enhance metadata handling for Arylic and LinkPlay renderers

Update version from 0.3.19 to 0.3.20

- Enhanced metadata handling in ArylicTcpRenderer and LinkPlayRenderer to use queue metadata for consistent duration protection
- Added shared queue functionality for HybridUpnpArylic to synchronize metadata between UPnP and Arylic backends
- Improved error logging and debug information for playback position fetching
- Updated version in Cargo.toml and version.txt
