# app/modules/enums.py
"""
Module system enums.

This file contains enums used by the module system that need to be
importable without triggering database model imports.

The FrontendType enum is defined here to break a circular import:
- app.modules.base imports FrontendType
- Previously FrontendType was in models.database.admin_menu_config
- Importing from models.database triggers model discovery
- Model discovery imports module definitions
- Module definitions import from app.modules.base → CIRCULAR

By defining FrontendType here, we break this cycle.
