repository.sh takes the URL positionally (name is derived from it), clones over
https, and defaults to the stable branch — which this repo does not have.
README, a module-catalog.json validated against TAPPaaS's
module-catalog-fields.json, and the podman module copied verbatim from
Community/src/larsrossen/containers/podman into a flat src/containers/ layout
(the catalog carries the explicit moduleJson path, so layout is free).
