Minimal reproducer for astral-sh/ty#3833
This is a dependency-free reduction of astral-sh/ty#3833, which reports that ty hangs while resolving pandas.Series.__mul__ against a NumPy ndarray when using NumPy 2.5.0's stubs.
GitHub Gists have a flat filename namespace, so the two stub files have path-prefixed names here. Restore the package layout before running ty:
mkdir -p numpy/_typing
