String-driven response-geometry log map: parse the user label (with shape
inference from the response column count), pick the base point (intrinsic
Fréchet mean when base is None), map every row to its tangent, and report
the canonical resolved label. This is the curved-manifold analogue of the
sphere/simplex dispatch and the single entry the FFI calls for these
geometries.
