🔄 CI/CD Deployment

Automated deployment pipeline on every push to main:

1. Build Docker image with application code and dependencies
2. Push to GitHub Container Registry (GHCR)
3. SSH to production server
4. Pull latest image and gracefully restart services
5. Run database migrations, collect static files, compile translations

Zero-downtime deployment ensures continuous availability.
