v2.12.0 - Wormhole cross-check vs. arXiv:2604.10090's ensemble-robustness claim (Experiment 10)

Direct comparison against the source paper's own 'Ensemble robustness' section, which claims the sign-dependent asymmetry is 'a generic feature of the ensemble' from 100 disorder realizations. Controlling for a real confound in Experiment 8 (its baseline point was itself tuned on seed=61), re-evaluating all 6 of our 34/11-selection-matched instances at the paper's own stated default parameters (t0=0.3, mu=12, t1=0.60) still leaves 2 of 6 instances wrong-signed -- directly contradicting the 'generic feature' claim for this subset. Seed 2166 is wrong-signed at every evaluation point tested across this whole write-up. See README Section 21 / docs/wormhole_syk_teleportation.md.
