🔧 Improve file transfer system integration and message handling

- File Transfer Integration: Refactored file transfer system initialization with better error handling and automatic retry mechanisms
- Message Filtering: Added comprehensive message filtering system to prevent file transfer and system messages from appearing in chat UI
- Callback System: Simplified file transfer callback system - removed progress notifications from chat to reduce noise
- System Message Deduplication: Implemented notification flags to prevent duplicate system messages (verification, security upgrades, etc.)
- Error Handling: Enhanced error handling with graceful fallbacks instead of throwing exceptions that could break connections
- UI Message Delivery: Added `deliverMessageToUI()` method with built-in filtering for system/file messages
- DataChannel Event Handling: Improved onmessage handler with early filtering for file transfer messages
- Global Integration: Better integration with global file transfer system (`window.fileTransferSystem`)
- Connection Stability: Removed aggressive reconnection attempts that could cause session closure
- Debug Logging: Enhanced debug logging for better troubleshooting

- File transfer messages now bypass chat UI entirely
- System messages are deduplicated using internal flags
- Better separation of concerns between WebRTC and file transfer systems
- More robust initialization sequence with proper cleanup
- Improved message routing and processing pipeline

- Fixed duplicate system notifications
- Resolved file transfer message leakage into chat
- Improved connection state management
- Better handling of initialization race conditions

+- **ECDH P-384** key exchange
+- **AES-GCM 256-bit** encryption
+- **ECDSA P-384** digital signatures
+- **Perfect Forward Secrecy** with key rotation
+- **MITM protection** via out-of-band verification
+- **Zero server architecture** (pure P2P)
+
+### Known Limitations
+- WebRTC fingerprinting possibilities
+- Browser-based implementation constraints
+- Dependency on Web Crypto API security
+- No protection against compromised endpoints
+- Traffic analysis potential despite encryption
+
+---
+
+## 🔄 Future Development
+
+### Post-Quantum Roadmap
+- **v5.0**: CRYSTALS-Kyber/Dilithium implementation
+- **Long-term**: Resistance to quantum cryptanalysis
+- **Ongoing**: Security audits and improvements
+
+---
+
+## 📞 Contact and Reporting
+
+### Security Issues
+- **Responsible disclosure**: Email security issues to the development team
+- **CVE reporting**: We participate in responsible vulnerability disclosure
