Cancel pending AI turns when restarting

When the player hits “重开” during the 450 ms AI delay, this timeout is still queued while startGame() resets gameOver and the board, so the old playComputerTurn runs against the fresh game and immediately places an AI domino before the player moves. Store/clear the timer on reset or guard it with a turn/game token so restarting always leaves an empty board.
