Export Selection… (file.exportSelection, a UI command) now collects the
selected objects as assets, one per object (multiple: false makes one),
reusing assets of art already collected, and opens Export for Screens on
its Assets tab with just those checked. document.exportSelection stays the
one-shot export for agents and scripts.
