Subject: [PATCH] ci: Add Docker build check to catch Dockerfile issues early
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add docker-build job that runs on every push/PR
- Builds only amd64 platform for speed (vs multi-platform in release)
- Uses GitHub Actions cache for faster builds
- Prevents Dockerfile issues from reaching release workflow
