ai.ModelTurnInput -> the serialized generateContent body.
The last step is always ai.wire.merge_request_body, so request_body
overrides everything the typed request built (and a null value in it DELETES
the key the client injected).
fetch_url is the backend's media strategy (see _gm_media_part): the
Developer API inlines http(s) media, Vertex passes the URL through.
