A module is a package, not a bare manifest

Each module becomes modules/<name>/ holding module.json, with room for
the rest of what a module is — its tools, health checks, provisioning,
lifecycle — which the conversion from hal still has to bring across.
The flat <name>.json was only the resource-declaration half.
