Cancel pending AI turns on reset

When Reset is clicked during the 350 ms Cyan delay, this timeout still fires against the freshly reset board. Because resetGame() restores turn to "P", the stale playComputerTurn() moves a Cyan stack while Pink is supposed to be choosing and moveStack() credits any overflow to Pink, corrupting the new game state immediately after reset. Store the timer id and clear it on reset, or guard the callback so old turns cannot run after a reset.
