First phase:

- cut and save each source tile; - stream its raw boundary data to a compact temporary binary file; - do not retain PlaneCutPoint or FrontierCandidate objects globally.

Second phase:

- build the final CellGrid3D instances from the generated TileInfo lists; - read each temporary boundary file in parallel; - build mergeable per-cell accumulators; - merge those accumulators sequentially; - create the final LodBoundaryAnchors.
