/**
 * Save terminal-completed run outputs to disk via a path template.
 *
 * Convention follows `genmedia run --download` / `gh release download` /
 * Stripe CLI artifact templates: explicit template with `{var}`
 * placeholders, auto-create parent dirs, return per-output local paths
 * so callers can surface them in JSON envelopes.
 *
 * Supported placeholders in `template`:
 *   {runId}  — the run UUID
 *   {index}  — 0-based output index (REQUIRED when there are 2+ outputs
 *              to prevent collisions)
 *   {ext}    — file extension inferred from URL pathname or `Content-Type`
 *   {label}  — slugified output label (apps surface meaningful labels;
 *              recipes use the variant `styleHint`). Falls back to "output".
 *
 * Example: `--download "./out/{runId}_{index}.{ext}"`.
 *
 * Failed / non-image-url outputs are skipped silently; the caller's
 * non-JSON renderer can flag them. The return value is just the list
 * of downloads that actually completed.
