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.

+## 🥚 Hidden Easter Eggs
+
+GlitchCraft contains several hidden easter eggs for the curious:
+
+### 🌩️ "He Comes" Mode
+- **Trigger**: Type `he comes` or `zalgo`
+- **Effect**: Auto-switches to Heavy Corruption with max intensity + red flash
+- **Reference**: Original zalgo creepypasta
+
+### 🔍 404 Text Not Found  
+- **Trigger**: Type `404`
+- **Effect**: Shows "T̷̢̧e̴̢̧x̷̰t̸̨̧ ̷̢̧n̴̢̧o̷̰t̸̨̧ ̷̢̧f̴̢̧o̷̰ų̸̧n̷̢̧d̴̢̧"
+- **Bonus**: Copy notification says "Error copied successfully!"
+
+### 💊 Matrix Mode
+- **Red Pill**: Type `red pill` → Heavy corruption + red tint + "Welcome to the real world"
+- **Blue Pill**: Type `blue pill` → Calm mode + blue tint + "You chose... wisely"
+- **Reference**: The Matrix (1999)
+
+### 👨‍💻 Developer Credits
+- **Trigger**: Type `credits` OR click the title 10 times rapidly
+- **Effect**: Shows corrupted developer credits
+
+### 🌙 Witching Hour (3:33 AM)
+- **Trigger**: Use the app at exactly 3:33 AM (any timezone)
+- **Effect**: Dark theme + screen shake + subtitle becomes "T̷̢̧h̴̢̧ḛ̷ ̸̨̧w̷̢̧i̴̢̧t̷̰c̸̨̧h̷̢̧i̴̢̧n̷̰g̸̨̧ ̷̢̧h̴̢̧o̷̰ų̸̧r̷̢̧"
+- **Duration**: Lasts for 1 minute
+
+### 📱 Mobile Shake
+- **Trigger**: Shake your phone/device
+- **Effect**: Random corruption mode + intensity + haptic feedback
+- **Message**: "S̷̢̧h̴̢̧a̷̰k̸̨̧e̷̢̧n̴̢̧,̷̰ ̸̨̧n̷̢̧o̴̢̧t̷̰ ̸̨̧s̷̢̧t̴̢̧ḭ̷r̸̨̧r̷̢̧e̴̢̧d̷̰"
