description	multi-arch image publishing to GHCR via GitHub Actions

Skill: Docker image publishing

Goal

Provide a reusable GitHub Actions workflow to build/push multi-arch images to GHCR on tag pushes.

Conventions

• Publish on tags v*.
• Use native Intel or ARM runners for CI/CD. Don't use QEMU.
• Use buildx + per-arch digest builds, then merge into a manifest.
• Use docker/metadata-action for semver tag derivation.

Files

• .github/workflows/publish.yml (consolidated: build, merge, prune, cleanup)
