Samuel Bouchet dac63e3be5 Phase 6.2: toping BLAS shadows + adaptive TMin + perf optimization 
- Re-enable toping BLAS in TLAS (3 instances: blocky + smooth + topings)
  with PREFER_FAST_TRACE for optimized BVH traversal (23M tris)
- Separate shadow/AO ray origins: shadow uses worldPos directly (zero bias),
  AO keeps normal bias (0.15) for hemisphere self-avoidance
- Adaptive TMin solves self-hit vs gap dilemma:
  ground (N.y≈1) → TMin=0.002 for tight blade shadows,
  blade surfaces (N.y≈0) → TMin=0.10 to skip own geometry
- Shadow rays 4→3 with tight cone (0.012 rad), AO rays 8→4
  (7 total rays/pixel, temporal accumulation compensates)
- Remove screen-space contact shadows (doesn't work for thin geometry)
