Remove debug print from is_game_over() causing stdout spam

Bug: The is_game_over() function contained a debug print statement that was
printing "1: " to stdout on every call. This was causing massive log spam
in Docker container output (thousands of lines) and making it difficult to
diagnose actual issues.

Fix: Remove the print(f'1: ') statement from line 3251.
