feat(io): Add Gmsh mesh reader for tetrahedral meshes
- GmshMesh struct: nodes, elements, physical_groups storage
- read_gmsh_mesh() parses ASCII format 4.1 (.msh files)
- Extracts Tet4 elements (type 4) and node coordinates
- Reads physical groups for boundary conditions
- get_surface_nodes() placeholder for BC node extraction
- 175 lines: Simple mesh I/O for demos and benchmarks
