v1.0.2: Mood mix optimizations and media player improvements

- Fixed player seek flicker on podcasts (30s skip buttons)
- Added dual-layer seek lock mechanism to prevent stale time updates
- Optimized cached podcast seeking (direct seek before reload fallback)
- Large skips now execute immediately for responsive feel
- Mood mix performance optimizations
