cvxgrp/cvxcla

Ran experiments/inverse_cla.py (documented usage: 'uv run python experiments/inverse_cla.py # verify vs cvxcla'), which computes CLA turning points with cvxcla and checks weights against an independent incremental-inverse baseline for n=20,40,80,160; all cases print [OK] with max|dw| ~1e-14.
