 * Cross-references installed plugins against the marketplace catalog to find
 * which have a newer version available, keyed by plugin id. Used by the
 * Installed tab to show an Update button on rows with a pending update.
 *
 * The catalog already computes install_state per entry (the backend joins the
 * catalog against installed records by id+version), so this hook just keeps the
 * `update_available` entries. Failures are swallowed — a missing/offline
 * marketplace must never break installed-plugin management; it just means no
 * update badges are shown.
