Developer Workflow

1. Developer pushes code to Gitea 2. Gitea Actions runs CI pipeline (lint, test, build, Trivy security scan) 3. Docker image pushed to Gitea container registry 4. CD pipeline deploys to production via Docker Compose 5. Traefik automatically routes traffic 6. Grafana monitors health metrics 7. n8n sends deployment notification to Slack
