Add architecture rule that detects when API routes import database
models directly, enforcing Routes → Services → Models pattern.
Changes:
- Add API-007 rule to .architecture-rules/api.yaml
- Add _check_no_model_imports() validation to validator script
- Update customer imports to use canonical module location
- Add storefront module restructure implementation plan
The validator now detects 81 violations across 67 API files where
database models are imported directly instead of going through
services. This is Phase 1 of the storefront restructure plan.
