feat: Complete Docker deployment environment for PyGuardian v2.1.0

🐳 DOCKER DEPLOYMENT INFRASTRUCTURE:

## New Docker Files:
- deployment/docker/Dockerfile.optimized - Multi-stage optimized builds
- docker-compose.prod.yml - Production cluster deployment
- docker-compose.dev.yml - Development environment
- deploy-docker.sh - One-command deployment script
- Makefile.docker - Advanced management commands
- .env.docker - Environment configuration template
- DOCKER_DEPLOYMENT.md - Complete deployment guide

## Container Images:
- pyguardian:controller - Cluster management (200MB)
- pyguardian:agent - Security monitoring (180MB)
- pyguardian:standalone - All-in-one deployment (220MB)
- pyguardian:development - Dev tools + Jupyter (350MB)

## Deployment Modes:
- Standalone: Single container with all features
- Cluster: Controller + scalable agents with JWT auth
- Production: Enterprise deployment with monitoring
- Development: Hot reload + debugging tools

## Key Features:
✅ Multi-stage Docker builds for optimization
✅ Privileged containers for system monitoring
✅ Host networking for firewall integration
✅ Volume persistence for data/logs/config
✅ Health checks and auto-restart
✅ Prometheus monitoring integration
✅ SSL/TLS support with custom certificates
✅ Automated backup and restore
✅ CI/CD ready builds

## Quick Commands:
./deploy-docker.sh standalone          # Quick start
./deploy-docker.sh cluster --scale 3   # Production cluster
make -f Makefile.docker prod-up        # Advanced management
make -f Makefile.docker health         # Health checks

Ready for enterprise Docker deployment! 🚀
