Joomla's ModuleAdapter requires the `module` attribute on a <files> child to identify the module element. Without it, install fails with "No module file specified" even when namespace and services/provider.php are present. Pattern confirmed against MokoSuiteClient modules. Also hardcodes the package description since packages don't load language files during install, causing the raw key to display. Authored-by: Moko Consulting
