Rewrote voxelSmoothPS.hlsl to derive a dominant face axis from the smooth normal, then use the exact same neighbor verification as voxelPS.hlsl: faceU/faceV tangent tables, stair-priority getNeighborMat(), face-aligned fractional coords, blendZone 0.25, corner attenuation, bleedMask checks. Added generateDebugSmooth() with 11 isolated test configurations (smooth↔blocky transitions, staircases, surrounded patches, reference blocky pairs). Launch with: BVLEVoxels.exe debugsmooth
