Migration from the predecessor

The predecessor project mixed compatibility work with broader runtime and verification concerns. OmniSolver MAPDL Interop starts from a separate history and retains only the file-interface boundary: resolved text model conversion, neutral read/write, and the MIT-licensed documented binary readers.

Use omni_solver_interop_mapdl.read_dat instead of a replay/runtime entry point. Use to_omnisolver_model or an application ModelSink to hand the neutral model to another system. Saved databases, geometry/mesh generation, procedural APDL execution, and solver-answer parity are intentionally not migrated.

The old repository is archived after the first OmniSolver MAPDL Interop release so historical links remain readable without presenting it as the supported implementation.
