Skill: Docker image publishing

Goal

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

Conventions

• 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.
