Extract MCP-related helper functions (renderEnv, mkEnvFilesWrapper, wrapEnvFilesCommand, addType, transformMcpServer) into a new shared library module at modules/lib/mcp.nix. - Add lib.hm.mcp for sharing transformMcpServer logic across consumers - Add enabled/disabled conflict detection assertion - Add tests for new library functions
