CI/CD

Docker images are automatically built and published to GitHub Container Registry (GHCR) when a tag matching v* is pushed.

The GitHub Actions workflow:

1. Checks out the repository
2. Generates Docker metadata tags (semver + latest)
3. Sets up QEMU for multi-architecture builds
4. Logs into GHCR
5. Builds and pushes images for linux/amd64 and linux/arm64

Usage:

git tag v1.0.0
git push origin v1.0.0

The image will be published to ghcr.io/<your-username>/ipv6-subnet-proxy.
