refactor(player): remove legacy UnifiedPlayer, GStreamer now mandatory

- Removed unified_ffmpeg_player.go and unified_player_adapter.go - Updated frame_player_gstreamer.go to remove UnifiedPlayer fallback - Updated frame_player_default.go to return error when GStreamer unavailable - Updated PROJECT_STATUS.md: Player module now fully implemented with GStreamer - Removed critical issues note about Player A/V sync problems GStreamer is now the sole playback backend, providing stable A/V synchronization and frame-accurate seeking. The broken FFmpeg pipe-based UnifiedPlayer has been completely removed.
