/**
 * The "Ask Claude" file action, loaded on every Files page view, and the
 * Text editor's Assistant fallback, loaded wherever Text can open.
 *
 * Built separately from vite.config.js so it shares no chunks with the app
 * bundle: there the bundler would link it to vendor-nextcloud-vue, and every
 * Files page would load the whole component library and its stylesheet just to
 * register one menu entry. Here the entry pulls in only @nextcloud/files and
 * l10n; the modal and its dependencies load on first click.
 *
 * Runs after the main build and writes next to it without emptying js/dist.
 * The entries are not in the main manifest, so ViteAssets falls back to
 * js/dist/<entry>.js, and they have no static stylesheet to link.
