upload_asset_from_url
Ingest an image asset from a public https URL: reachable without authentication, resolving to a public IP (SSRF guards), never a chat attachment. Deduped by content hash — identical bytes set `dedupe` true and write no new storage. Optional name/description/tags use the update_asset_metadata caps.
