Extends PROVIDER_STREAM_PARSE_MARKERS (single home) with jiter's serde
vocabulary and excludes those ValueErrors from _is_local_validation_error so
the turn-level retry/fallback path runs instead of aborting as a local bug.
Grafted from #65154 (its conversation_loop regex is superseded by the markers).
