Give every plugin artwork per-instance SVG def ids via useId so repeats on
one page keep their gradients and clips; drop the dead agent-team-web-profile
artwork row; keep the read-failure alert and retry visible on detail pages;
cover the new artwork components and the default-artwork branch; document the
artwork exports in the ui-primitives READMEs; refresh the plugin-manager and
plugin-install-cancel web expected outputs for the revised copy.
