hex_mesh_cells meshes cells that meet face to face (SolidCraft split
bodies) as one conforming all-hex mesh: each cell a mapped block after
smoothly meeting faces are joined (virtual topology: the halves of a hole,
a plane running into a fillet), vertices, edges and faces shared by
identity, interval assignment over all cells, each shared face meshed
once, radial edges graded off curved faces. finish spans several cells:
tags per cell, hex20 mid-edge nodes shared across cells, a closed
2-manifold boundary and no free internal face.
