Weekly upgrade: v3.1 with SaveSystem, AchievementSystem, and enhanced AudioSystem

[Copilot]

Weekly framework upgrade adding game state persistence, achievement tracking, and enhanced audio capabilities. All changes are backward compatible.

New Systems

SaveSystem (framework/utils/SaveSystem.js)

• Multi-slot save/load with localStorage backend (configurable slots, default 3)
• Auto-save with configurable intervals
• Export/import for save data portability
• Storage statistics and validation

const saveSystem = new SaveSystem({ gameId: 'my_game', maxSlots: 3, autoSave: true });
saveSystem.save(0, gameState, { level: 5, playtime: 3600 });
const loaded = saveSystem.load(0);
saveSystem.startAutoSave(() => getCurrentState(), 0);

AchievementSystem (framework/systems/AchievementSystem.js)

• Four achievement types: simple, progress, secret, challenge
• Progress tracking with percentage calculation and callbacks
• localStorage persistence with gameId scoping

const achievements = new AchievementSystem({ gameId: 'my_game' });
achievements.registerAchievement({
  id: 'kill_100', name: 'Centurion', type: 'progress', target: 100
});
achievements.incrementProgress('kill_100', 1);
achievements.onUnlock(achievement => giveReward(achievement.reward));

AudioSystem Enhancements

• preloadSounds() - batch audio loading
• fadeInAmbient(), fadeOutAmbient(), fadeAmbientTo() - smooth transitions
• playSpatialSound(), updateSpatialSound() - distance-based volume
• setAmbientVolume(), getAmbientVolume() - runtime volume control
