Replaces the Jenkinsfile with a .gitea/workflows/build-push.yml that builds on pushes to main and pushes `latest` + `sha-<short>` tags to the Gitea package registry using the REGISTRY_URL variable and REGISTRY_TOKEN secret. Adds a docker-compose.yml that pulls the published image for deployment. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
