EvoScientist/tests/registry_fixtures.py

"""Shared builders for model-registry integration tests.

Centralizes the "active registry + verified models + snapshot" fixture
graph so middleware and runtime tests don't each re-derive the RegistryV4
payloads. Mirrors the fixtures in ``tests/test_snapshots.py``; that module
keeps its own copies to stay self-contained (Task 4 deliverable).
