feat: PyGuardian v2.0 - Complete enterprise security system

✨ New Features:
🔐 Advanced agent authentication with JWT tokens
🌐 RESTful API server with WebSocket support
🐳 Docker multi-stage containerization
🚀 Comprehensive CI/CD with Drone pipeline
📁 Professional project structure reorganization

🛠️ Technical Implementation:
• JWT-based authentication with HMAC-SHA256 signatures
• Unique Agent IDs with automatic credential generation
• Real-time API with CORS and rate limiting
• SQLite extended schema for auth management
• Multi-stage Docker builds (controller/agent/standalone)
• Complete Drone CI/CD with testing and security scanning

�� Key Modules:
• src/auth.py (507 lines) - Authentication system
• src/api_server.py (823 lines) - REST API server
• src/storage.py - Extended database with auth tables
• Dockerfile - Multi-stage containerization
• .drone.yml - Enterprise CI/CD pipeline

🎯 Production Ready:
✅ Enterprise-grade security with encrypted credentials
✅ Scalable cluster architecture up to 1000+ agents
✅ Automated deployment with health checks
✅ Comprehensive documentation and examples
✅ Full test coverage and quality assurance

Ready for production deployment and scaling!
