 * These exercise the non-destructive paths only: --help and --dry-run. The
 * --dry-run path resolves the renderer (validating it against the registry and
 * reading manifest.template) and prints the scaffold plan without invoking any
 * `pnpm create` / network calls, which keeps the test hermetic and fast.
