"""
Database models package.

This package imports all SQLAlchemy models to ensure they are registered
with Base.metadata. This includes:
1. Core models (defined in this directory)
2. Module models (discovered from app/modules/<module>/models/)

Module Model Discovery:
- Modules can define their own models in app/modules/<module>/models/
- These are automatically imported when this package loads
- Module models must use `from app.core.database import Base`
