feat(physics): torsion = RG rotation, frame-drags spacetime at extreme scales

RGManifoldSeams.lean:
  The SM coupling manifold has intrinsic torsion omega = 0.05775 rad/e-fold,
  derived from 5 CERN-measured couplings. At extreme scales (BH interiors,
  Planck scale), this torsion couples to spacetime via Einstein-Cartan:
    torsion ∝ omega * H(z)
  The seam at lambda = 0 is where torsion-spacetime coupling becomes order 1.
  Above: torsion dominates (frame-dragging). Below: curvature dominates (GR).

ClusterBHAnchors.lean:
  Void fraction between cluster (~5 Mpc, n=3) and BAO (~147 Mpc, n=4) scales:
    59% → 70% — consistent with DESI observed void fractions.
  Model s8 = 0.812: consistent with DES+SPT (0.795, 0.6s).
                    tension with Planck SZ (0.77, 2.1s).
  BH M-sigma: Koch under-predicts exponent by 5x — genuine failure mode.
