Samuel Bouchet 3d0c4f2f80 Phase 4.2+7: grass blade rework + soft RT shadows + toping BLAS optimization 
Grass blades:
- Leaf-shaped profile (4 sections: base→belly→taper→tip) instead of spiky triangles
- Wider blades (base 0.055-0.095), more spacing between blades (±0.07 scatter)
- Natural green texture (50,140,35 → 80,180,55) instead of neon lime
- Reduced warm shift and removed artificial saturation boost
- Side faces at 60% brightness (dark green) instead of 38% (near-black)

Soft RT shadows:
- 2 jittered shadow rays per pixel with IGN+Cranley-Patterson temporal variation
- 2.3° cone around sun direction for soft penumbra
- Gradual shadow factor (0-100%) instead of binary on/off

Performance:
- Toping BLAS removed from TLAS (23M+ tris caused massive ray traversal slowdown)
- Toping BLAS position/index buffer construction skipped entirely
- Shadow rays reduced from 4 to 2 (temporal accumulation compensates)
