Fixes
- Assembly Version Fixed: DLL now correctly reports v1.2.8.0 instead of v1.2.7.0
- Sidebar Link Fixed: Converted from anchor to button element, preventing Jellyfin's SPA router from intercepting the click
- Jellyfin Native Integration: 'Enable Theme Songs' now reads/writes Jellyfin's native DisplayPreferences setting - syncs with Settings > Display > Libraries
- Volume Control: Now properly applies via HTMLMediaElement.prototype.play interception
- Duration Limit: Max duration watchdog works correctly
