"""Root conftest — ensures the project root is on sys.path.

Required when the virtual-environment Python is symlinked to an external
interpreter (e.g. Anaconda) that does not process the venv's .pth files
automatically.  Adding the project root here makes ``codex`` importable
regardless of how pytest is invoked (``pytest``, ``python -m pytest``, etc.).
