Subject: [PATCH] feat(ci): improve Docker workflow with Buildx, caching and
 semver tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add Docker Buildx for multi-arch support
- Enable GitHub Actions cache for faster builds
- Add semver tagging for version releases (v*)
