Version 7.9.1

Patch release: object diagram attributes are no longer dropped when exporting to PNG or SVG. This is a frontend-only release — no metamodel, generator, or backend API changes; the only backend-repo change is the web-modeling-editor submodule pointer bump.

Fixes

• Object diagrams exported as empty header boxes: the export-only SVG scene (packages/editor/src/main/scenes/svg.tsx) special-cased only UMLClassifierComponent to nest its member children (attributes and methods) inside the box. Object boxes render through UMLObjectNameComponent, which fell into the default branch and was drawn alone, while each object’s ObjectAttribute / ObjectMethod members — mapped to UMLClassifierMemberComponent — hit the skipped member case on the assumption they had already been nested inside a classifier. They never were, so exported object diagrams showed a white header box with no attribute rows. The live editor canvas was unaffected because it renders container children directly; only the export path special-cased the classifier. The fix routes UMLObjectNameComponent through the same member-nesting branch as UMLClassifierComponent. Matching on the component (rather than the element type) also covers UserModelName, which maps to the same component. PNG export rasterizes the result of exportAsSVG, so both formats are fixed by the single change.
