`output_public_url`

Create public MP4 review and download links

Creates expiring public review and direct-download URLs for one exact finished BitterClip render. The review URL is the practical human handoff; download_url remains the primitive for external services that ingest a public video URL (captioning/styling connectors like Submagic, Zapier steps, publishing tools). It takes exactly ONE target: episode_id for an Episode/derived-clip handle, OR render_id for a ready render artifact alone; never both. A derived clip's comp_... handle goes in episode_id. This tool never starts or retries rendering: render_not_ready means render_status has not yet reported the render_create lifecycle ready. Repeating the call for the same ready render is safe and does not enqueue or mutate a render; it only returns fresh expiring bearer URLs. A later render invalidates these links rather than silently showing a different cut. A UI-supplied expected_render_generation makes a stale card fail instead of sharing a newer Render. title and dictionary give a receiving service context for download_url.
