FN-6085: avoid dashboard CSS import in plugin entry

Prevent the Compound Engineering plugin from pulling dashboard CSS into Node-side plugin loading.

- remove the dashboard view re-export from the Compound Engineering plugin server entry
- document the CSS-import failure mode caused by server-side index re-exports of dashboard views
- update bundled plugin registration guidance to keep dashboard view loading client-only
