plt.axes(projection="3d") is typed to return the base 2D Axes, so ax.scatter's 3rd positional argument (meant as zs) was resolving against 2D Axes.scatter's s parameter and colliding with the explicit s=100 kwarg — this was the repo's only parameter-already-assigned diagnostic. Cast ax to Axes3D so ty resolves the correct (xs, ys, zs, ...) overload instead (no runtime behavior change), and un-ignore the rule in pyproject.toml now that its diagnostic count is zero repo-wide.

Part of #15187 (supersedes #15460, which I accidentally left with an unmarked checklist)

So much difficult to understand 😕

We need type hints for data, centroids, and cluster_assignment
