uv falls back to pip install on runners without uv binary, so this
change is forward-compatible with the current ci-python image. When
the runner image gets uv pre-installed in a future bump, the warm
install path drops from ~2 min to ~10 seconds.
pytest-xdist parallelization is OUT OF SCOPE for this commit:
tests/conftest.py uses a TRUNCATE ALL TABLES RESTART IDENTITY CASCADE
fixture after every integration test against a single shared
database; xdist workers running in parallel would nuke each other's
mid-test state. A future refactor to per-worker databases or
per-worker schema isolation is the prerequisite.
