/**
 * Built-in plugin catalog data-integrity tests (both files: the TAB
 * catalog in plugins-tabs.ts and the FILE-PREVIEWER catalog in
 * plugins-viewers.ts). Every entry must be installable as data — a unique
 * id (npm package name), a GitHub URL, a non-empty localized name and
 * description (string or () => string), and an install script that mentions
 * the dsh plugin CLI. The catalogs are the discovery surface of the two
 * "add plugin" modals; a malformed entry would break the install flow, so
 * the shape is pinned here.
