Snake: add full border frame and pause/resume with session persistence
- Full box border around title, game area, and instructions - ESC pauses and saves state to session via pi.appendEntry() - Resume shows 'PAUSED - press any key to continue' - Q quits and clears saved state - High score persists across games
