Recompute the v4 recipe comparison once instead of per feature (148 s to 6 s) and compare bounding boxes as well as volumes; drop the incidental NaN loop from the unrepairable Voronoi case; prove the renamed preset is the one selected instead of checking a dirty flag that selecting clears; tell sparse from empty infill in the solid-shell test; plus smaller cleanups.
