check_auto_complete no longer requires the waste pile to be empty —
only the stock must be exhausted and all tableau cards face-up.
next_auto_complete_move checks the waste top card before scanning
tableau, and auto_complete_step falls back to draw() when no direct
foundation move is available so the waste drains automatically.
Fixes the end-game state where the player could see a clear win but
the auto-complete interval never fired because the waste was non-empty.
