Migrate to Podman, Forgejo Actions; clean up cruft
Container:
- Dockerfile → Containerfile; drop gosu, entrypoint, PUID/PGID user-switching
- HOME=/config so Path.home()/.aws resolves to runtime-mounted credentials
- docker-compose.yml → compose.yml with userns_mode: keep-id for Podman rootless
- .dockerignore → .containerignore
- boto3 unpinned from 1.34.0 to >=1.34.0
CI:
- Remove Woodpecker (.woodpecker.yml, .woodpecker/)
- Add Forgejo Actions (.forgejo/workflows/ci.yml, publish.yml)
- CI: syntax check, security scan, container lint (hadolint), build test
- Publish: build and push to Quay.io on main push and version tags
Cleanup:
- Remove entrypoint.sh (no longer needed)
- Remove scripts/build-and-push.sh and PUBLISHING.md (superseded by CI)
- All docker → podman command references updated
