Add unified Figure 2(a) C2ST/SBC/TARP audit

Claims [1][2][3]: general reproduction -- E[U]=1-AUC with trained classifiers across 6 families, O(eps^2/3) gap across 4 families, and SBC/TARP vs Conformal-C2ST detection-power benchmark

Reproduce Thm 3.5 (claim 1): conformal C2ST gap under classifier L2 error stays under O(eps^2/3) envelope; re-confirm H0 uniform + E[U]=1-AUC
