"""Installer accepts every manifest_version the runtime loader supports (#85879).

The installer used to carry its own private manifest-version cap, which
drifted behind the loader's ``SUPPORTED_MANIFEST_VERSION`` and refused v2
plugins the runtime happily loads. These tests install through the real
clone path so the two can never split again on the next bump.
