MODULE_AUTHORING

Built-in module authoring

A module declares a ModuleDescriptor and a cmd2.CommandSet in the explicit registry. Its console adapter delegates to a service; it must not open storage, read secrets, call providers, or implement business rules directly. Add the same argument parser action to the one-shot dispatcher and command set so behavior and errors remain identical. The user-facing command inventory belongs in the CLI reference, rather than module-specific documentation.

Modules are built-in only in v1. Add tests proving disabled modules are not imported, commands are unavailable, service DTOs serialize, secrets stay out of history, and offline defaults make no network calls.
