`ptwm_core::transforms::spherical_normalize`

SphericalNormalize — per-row (radius, direction) reparameterization with an exact XOR residual. Lossless by construction (the inverse reconstructs the prediction from the stored radius/direction and XORs the residual back, so float-op inaccuracy only affects residual size, never correctness).
