[DTP-Worker] Sprint 8 · Générateur Matrice de régression exhaustive (19 suites · 474 tests · gate méta-niveau) (QA · roadmap L74)

Harnais méta-niveau : agrège l'exécution de toutes les suites gated en une
matrice + verdict PASS/FAIL et fournit le compte agrégé faisant autorité
(N tests verts). Périmètre dérivé du CI (réutilise q4lib/registry.parse_ci ·
zéro duplication) ; anti-invention (#6) : le plan ne contient aucun compteur de
résultat, recomputé à la validation. Enregistré dans l'audit 4Big (18→19
modules · PASS 19/19). run exhaustif : 19/19 suites vertes · 474 tests passés.
