feat: create production docker-compose.yml (#38)

- Production compose file with single app service
- Separate from development compose (now docker-compose.dev.yml)
- Environment variable configuration
- Health checks and resource limits
- .env.production.example template
- Comprehensive DEPLOYMENT.md guide

Deployment guide covers:
- Quick start with Docker Compose
- Supabase setup (cloud + self-hosted)
- Multiple deployment options (Coolify, Docker, K8s, VPS)
- HTTPS/SSL configuration
- Monitoring and logging
- Backup and restore procedures
- Troubleshooting
- Security checklist
- Performance optimization

Ready for production deployment on any platform.

Closes #38
