fix(mesh): align Hex8 refinement with Mesh{N,T} constructors

Browse Source 
Use explicit `Mesh{8, Hex8}` signatures, SPDX banner lines, and the keyword
`Mesh{T}(nodes, conn; ...)` outer constructor after the mesh core refactor.

- Update docstrings and method signatures from `Mesh{Hex8}` to `Mesh{8, Hex8}`.
- Build refined meshes via `element_sets`/`node_sets` keywords.
