wassname f91c7b23f2 antipasto: add EVA-style data-driven group_init ...

Weight-SVD init (PiSSA-style) kept as fallback; when calibration_data is
provided, group_init() collects pre-hook activations, SVDs the pooled inputs
per layer, and re-decomposes W_orig through the top-r input-PCA directions.
Vhr_final = Vh_A @ Vhr_new keeps rows orthonormal while preserving the
input-aligned span.
