/**
 * Raw app workspace dependencies
 *
 * A raw app keeps its runnables in `backend/`, not in `raw_app.yaml`. The
 * workspace dependency filtering must resolve those files, otherwise the
 * default `dependencies/package.json` is dropped and locks are regenerated
 * against unpinned versions.
 *
 * Exercised through the legacy (tree-less) path: tree mode sources its deps
 * from `getMismatchedWorkspaceDeps()`, which is only populated by an
 * `uploadScripts` round-trip, so it cannot run offline. Both paths filter the
 * same `appValue`, so resolving it correctly is what this pins.
