M4.13: export correctness and MCP export parity — document.export/serialize honour artboard, artboards or range ("1-3, 5") for PDF (one page per artboard) and return dataBase64 without a path; Export for Screens writes one page per PDF, ignores scale and @Nx suffixes for vector formats, names duplicate artboards -2/-3 and returns bytes without a folder; raster exports, thumbnails and Export Selection leave template layers out (RenderOptions.skip_templates); file.exportForScreens with params runs the engine; the MCP export tool takes artboard/range/options, lists formats from the engine and never retargets the document; CLI convert --range
