Cancel stale AI timeouts on reset

Because this timeout is not stored/cancelled or tied to a game generation, pressing New Game during the 260 ms AI delay resets the board while the old callback still runs against the fresh state. In that scenario the AI immediately makes a move in the new game, or interleaves with the player's first move, corrupting the reset game; clear the pending timeout or ignore stale callbacks when startGame() runs.
