Contract
- assert prepend mode mutates sys.path with root conftest dir allowing uninstalled imports
- assert importlib mode does not mutate sys.path and raises ModuleNotFoundError without pythonpath config
- assert configuring pythonpath=['.'] in pyproject.toml restores package importability under importlib mode
- assert duplicate test file names across folders collide in prepend mode but succeed in importlib mode
