jack 3070a4d307 Implement Noise Protocol Framework and peer ID rotation for enhanced security and privacy 
This major update replaces the basic encryption with the Noise Protocol Framework
and adds ephemeral peer ID rotation for enhanced privacy.

Key Changes:

Security Infrastructure:
- Implemented Noise Protocol Framework (XX handshake pattern)
- End-to-end encryption with forward secrecy and identity hiding
- Session management with automatic rekey support
- Channel encryption with password-derived keys

Privacy Enhancements:
- Ephemeral peer ID rotation (5-15 minute random intervals)
- Persistent identity through public key fingerprints
- Favorites and verification persist across ID rotations
- Block list based on fingerprints, not ephemeral IDs

Core Components Added:
- NoiseEncryptionService: Main encryption service
- NoiseSession: Individual peer session management
- NoiseChannelEncryption: Password-protected channel support
- SecureIdentityStateManager: Persistent identity storage
- FingerprintView: Visual fingerprint verification UI

Bug Fixes:
- Fixed handshake storm with tie-breaker mechanism
- Fixed missing connect messages during peer rotation
- Fixed delivery ACK compression issues
- Fixed race conditions in message queue
- Fixed nickname resolution for rotated peer IDs

Testing:
- Comprehensive test suite for Noise implementation
- Security validator tests
- Channel encryption tests
- Identity persistence tests
- Rate limiter tests

Documentation:
- BRING_THE_NOISE.md: Technical implementation details
- Updated WHITEPAPER.md: Simplified and focused on core innovations
- Removed temporary debug documentation

The implementation maintains backward compatibility while significantly
improving security and privacy. All existing features (channels, private
messages, favorites, blocking) work seamlessly with the new system.
