/**
 * Grep-safe output support for the media generation tools.
 *
 * Agents routinely pipe gsk stdout through `grep | head` to save context.
 * With indent-2 JSON the URL values sit on their own lines, so such
 * filters keep the `"image_urls": [` key line and silently drop the URLs
 * — the agent then reconstructs (fabricates) them from memory, which is
 * the prod broken-card incident behind PR #41690. Two defenses:
 *
 * 1. `mediaItemsKeyFor` marks these tools for compact (single-line)
 *    stdout — any line filter then keeps the whole payload.
 * 2. `mediaSummaryLines` produces stderr `[INFO]` lines carrying the
 *    fields the render card needs (task_id / status / first URL), so
 *    even a stdout-swallowing pipeline still surfaces them via 2>&1.
