Module gpu_marching_cubes 

GPU marching cubes compute pipeline (Phase 17). GPU marching cubes — Phase 17.

Three-pass GPU compute pipeline for isosurface extraction:

1. Classify — computes case index and triangle count per cell.
2. Prefix sum — hierarchical exclusive scan to build triangle offsets.
3. Generate — interpolates vertex positions and normals into a vertex buffer.

The output is drawn with a lightweight Phong render pipeline via draw_indirect.
