SysML v2 Co-Pilot

AI-native SysML v2 systems-engineering co-pilot. Authors valid textual SysML v2 (.sysml), grounds every type/unit in the standard library (ISQ, SI, …), and validates with the real SysML v2 Pilot compiler in a self-correcting loop. Bundles an MCP server (validate_sysml_file, query_library, get_library_element).
