Previously maxLimit was passed directly to setTimeout/setInterval (ms),
so a JSON value of 10 meant 10ms instead of the intended 10 seconds.
Now timeLimit in JSON represents seconds, engine multiplies by 1000.
The first onUpdate call used raw milliseconds (e.g. total: 10000),
while subsequent ticks used seconds (total: 10). This caused the
progress bar to jump on the first interval tick.

Replace auto-start after loading with a '开始游戏' button overlay.
The user click provides the required user gesture for autoplay with sound,
fixing the issue where play() was silently rejected and choices never appeared.
- Reorder onEnd callback before play() in Engine.goToScene to prevent
missed ended event if video ends synchronously
- Wait for loadedmetadata event in VideoManager.play() before seeking
to ensure currentTime reset works correctly on new video sources
