Cancel queued computer moves when resetting

When the player clicks Reset during the 450 ms computer delay, this queued callback still runs against the freshly reset state because the timeout is not stored or cleared. Since playNumber does not verify that it is actually the computer's turn, the stale callback injects a computer-selected number into the new game, initially treating it as the player's move and potentially scheduling another computer move. Store and clear the timeout on reset, or guard the callback with a game/version token.
