feat: Add comprehensive testing suite and fix CI/CD pipeline

🧪 Testing Infrastructure:
- Unit tests for authentication system with JWT validation
- Integration tests for API endpoints and cluster management
- End-to-end tests for complete workflows and performance
- Test runner script with pytest configuration
- pytest.ini with proper markers and settings

📚 Documentation:
- mkdocs.yml configuration for GitHub Pages deployment
- Professional documentation structure with Material theme
- Navigation for installation, architecture, and examples

�� CI/CD Pipeline Improvements:
- Fixed .drone.yml with proper test execution stages
- Added unit, integration, and e2e test steps
- Security scanning with Bandit and Safety
- Docker multi-stage builds for controller/agent
- Documentation deployment to GitHub Pages
- Performance testing and coverage reporting

✅ Test Coverage:
- Authentication system: JWT tokens, HMAC signatures, encryption
- Database operations: agent credentials, token management
- API integration: endpoints, middleware, WebSocket
- E2E workflows: registration, security incidents, monitoring
- Performance benchmarks: concurrent auth, API throughput

🛡️ Quality Assurance:
- Code linting with flake8, black, isort
- Security vulnerability scanning
- Container image security checks with Trivy
- Dependency safety verification
- Test coverage reporting with pytest-cov
