"""Test-suite defaults that must be set before any test module is imported.

`main.py` builds the entire runtime at module scope (`build_runtime(get_settings())`),
and `tests/test_api.py` imports `main`. With the default `EMBEDDING_PROVIDER=cohere-v4`
— or with a developer's `.env` selecting it — that construction opens a
`QdrantClient` and calls `get_collections()` for the corpus-manifest check, so
`pytest` fails during *collection* on any machine without a reachable Qdrant:

    qdrant_client.http.exceptions.ResponseHandlingException:
        [WinError 10061] No connection could be made ...
    Interrupted: 1 error during collection

No unit test needs a live datastore: every test injects its own doubles, and
the one suite that does need real services (`test_live_datastores.py`) gates
itself behind `RUN_INTEGRATION=1`. Forcing the disabled provider here makes
`pytest tests -q` work out of the box instead of requiring an undocumented
environment variable.

`setdefault`, not assignment: a deliberate override (for example
`EMBEDDING_PROVIDER=cohere-v4 pytest ...` against a local Qdrant) still wins.

This runs at import time, before pytest collects any module, which is the only
point early enough — `config.get_settings()` is `lru_cache`d, so a fixture
would already be too late.
