Add game_mode to create_memory with default ON

- create_memory now shows game-style results by default
- game_mode parameter added (default: true)
- Both create_memory and create_memory_with_ai now show game results
- Users can disable game mode with game_mode: false if needed

This ensures game-style display appears regardless of which tool Claude Code chooses.
