feat: implement audio seeking with arrow keys via ffplay restart

Browse Source 
Seek now works by restarting ffplay with -ss offset instead of the
broken player.seek() stub. MoveLeft/MoveRight added as aliases for
SeekBackward/SeekForward to fix HashMap non-deterministic iteration
order causing Left arrow to resolve to MoveLeft instead of SeekBackward.
