 * GPU-accelerated voxelization of Gaussian splat data into a block mask buffer.

 * (BVH queries + index copying) while the GPU executes the current one.
 *
 * @param bvh - Gaussian bounding volume hierarchy for spatial queries.
 * @param gpuVoxelization - GPU voxelization pipeline with Gaussians already uploaded.
 * @param gridBounds - Block-aligned grid bounds to voxelize within.
 * @param voxelResolution - Size of each voxel in world units.
 * @param opacityCutoff - Opacity threshold for solid voxels.
 * @returns Block mask buffer containing voxelization results.
