Overview

Downloads remote images referenced in ingested post HTML, stores them via ActiveStorage, and rewrites the body HTML so <img> src attributes point at locally-hosted ActiveStorage proxy URLs.

Supports two modes:

1. Explicit references: src="helios://image/<reference_key>" paired with
   an images_payload array containing download URLs.
2. Auto-import: any remaining src="https://..." URLs are downloaded,
   deduplicated by a SHA256 of the URL path.
