Browse Source 
stroid can now generate non uniformly refined vacuum meshes. Note we still enforce that the stellar domain is fully conforming.

* @brief Verifies the baseline block topology cardinalities in the no-vacuum case.
* @brief Verifies the default multi-block topology including the vacuum.
* @details
* Rationale: this is the fastest canary for accidental edits in block construction order,
* vertex indexing, or boundary-face assembly.
* Method: build the default skeleton and assert exact counts (3D, 16 vertices, 7 hexes, 6 bdr quads).
* Method: build the default skeleton and assert exact counts (3D, 32 vertices, 19 hexes, 12 bdr quads).
* If this fails: inspect `stroid::topology::BuildSkeleton` in `src/lib/topology/topology.cpp`,
* especially `add_box`, `stellar_shells`, and `surface_bdr_quads`, plus ID defaults in
* `src/include/stroid/config/config.h`.
