* feat: add Docker image build and push to GHCR on release
Add Dockerfile (multi-stage build with node:22-slim) and a new docker
job in the release workflow that builds and pushes to ghcr.io when
release-please creates a tag.
* feat(docker): run as non-root user and add smoke test
Run the container as a non-root appuser to reduce blast radius.
Add a smoke test step that runs --version before pushing to GHCR.
* fix(docker): use existing node user instead of creating appuser
