- Add starlette>=0.36 and httpx>=0.27 to dev dependencies so
test_openai_compat.py can run in dev environments
- Add pytest.importorskip guards for starlette and fastapi so the
test file is skipped gracefully when those packages are missing
- Fix import sorting (ruff I001)
340 tests now pass (was 325 with test_openai_compat skipped).
