When a user played an album, advanced a few tracks, closed the player,
then played a different album, playback started mid-album at the
previous track index instead of track 1.
The root cause was in reduceSyncQueue: the hasPendingSwitch check
compared playIndex against savedPlayIndex, but after clearQueue both
reset to 0, making the check falsely conclude no switch was pending.
This caused PLAYER_SYNC_QUEUE to prematurely clear the playIndex and
clear flags before the music player library could act on them.
Fix: also treat clear=true as a signal that a track switch is pending,
since it means a new queue was just loaded.
