Cancel pending AI turns when restarting

When the player clicks 重开 during the 420 ms AI-thinking window, this timeout is still queued; startGame() resets gameOver to false, so the old playComputerTurn runs against the fresh board and lets the AI place an unexpected first move. Repeating quick reset/move cycles can also leave multiple stale AI turns queued for the new game, so the reset button does not reliably start from an empty player-to-move state.
