feat: complete Phase 1-3 architecture optimization

Phase 1 - Security:
- Add AES-GCM encryption for localStorage fallback
- Enforce WSS protocol for non-localhost WebSocket connections
- Add URL sanitization to prevent XSS in markdown links

Phase 2 - Domain Reorganization:
- Create Intelligence Domain with Valtio store and caching
- Add unified intelligence-client for Rust backend integration
- Migrate from legacy agent-memory, heartbeat, reflection modules

Phase 3 - Core Optimization:
- Add virtual scrolling for ChatArea with react-window
- Implement LRU cache with TTL for intelligence operations
- Add message virtualization utilities

Additional:
- Add OpenFang compatibility test suite
- Update E2E test fixtures
- Add audit logging infrastructure
- Update project documentation and plans
