Subject: [PATCH] fix: prevent accidental new game start when mouse held during
 game end

When the cursor is held down during gameplay and the game ends, releasing
the mouse button would previously start a new game immediately. Now, a
fresh click (pointerdown + pointerup) is required to start a new game
from both the menu and gameover screens.

Uses a freshClickRef to track whether pointerdown occurred in a
non-playing phase before allowing pointerup to trigger a new game.
