fix(claude-code): inherit shared tutorials pytest.ini so test_utils imports

The per-tutorial [tool.pytest.ini_options] block (only asyncio_mode="auto")
made pytest treat the tutorial's own pyproject.toml as the rootdir config, so
examples/tutorials/pytest.ini (pythonpath=.) was never discovered and
`from test_utils...` failed with ModuleNotFoundError in the live test.
asyncio_mode="auto" was redundant: every async test already uses an explicit
@pytest.mark.asyncio marker.
