scripts/build-and-push.sh builds the native image with the Mandrel
Dockerfile and pushes it to a remote Docker host via docker-pussh
(unregistry), transferring only missing layers over SSH.
- Name and tag default to pom.xml artifactId/version (overridable)
- Builds for linux/amd64; --skip-build to pussh only
- Verifies image presence on the remote after push and prints
a ready-to-use docker run hint
README updated with a 'Building and deploying natively' section.
