`ptwm_core::transforms::alpha_stable_normalize`

AlphaStableNormalize — per-row robust affine normalization (v − δ)/γ with an exact XOR residual. δ = median(row), γ = median(|row − δ|) (MAD). Lossless by construction: the fit is encode-only, γ, δ are stored per row, and the residual repairs all round-off — so reconstruction is bit-exact regardless of the (heavy-tailed) distribution.

Lossless by construction: the fit is encode-only, `γ, δ` are stored per row, and the residual repairs all round-off — so reconstruction is bit-exact regardless of the (heavy-tailed) distribution.
