Replace Python-only centralizer verification with full Lean certificate:
- 47×47 pivot submatrix of combined constraint system (g₂ + ad(H₁) + ad(H₂))
- Rational right-inverse (199 non-zero entries, denominators in {1,2,3,4,6})
- native_decide over ℚ verifies product = I₄₇ → rank ≥ 47 → nullity ≤ 2
Testing on CI before merging to main (previous native_decide approach OOM'd runner).
