Add comprehensive easter egg system with mobile optimization

Implement 6 interactive easter eggs:
- "He Comes" mode (type "he comes" or "zalgo")
- 404 Text Not Found (type "404")
- Matrix red/blue pill modes
- Developer credits (type "credits" or click title 10x)
- Witching Hour (3:33 AM automatic activation)
- Mobile shake detection with haptic feedback

Fix easter egg trigger logic to prevent normal generation override.
Add complete documentation of all easter eggs in README.
