refactor(#11-Kritik): Contacts-Entities aus statischem Core-Registry entfernt — ContactsPlugin.get_entity_models() ist Single Source (contact/contacts/company); conftest spiegelt Produktions-Bootstrap idempotent (autouse-Fixture); Regressionstests beweisen Plugin-Registrierung; 12 ACL-Batch-Failures per Stash-Test als Vorbestand bewiesen (Suite-Isolation, identisch auf clean HEAD)
