message.complete frames with status "error" were detected only by a text
regex heuristic, which misses the gateway's "Error: <detail>" texts and
partial-text failures — a failed turn rendered as a healthy reply. The
structured error/partial fields now drive the failure state: the bubble is
marked failed from the frame's error field, and a partial failure keeps
its streamed text visible instead of stripping it. session.resume's
inflight projection likewise carries a retained failure's error onto the
projected assistant row, so a failed turn recovered after a disconnect
renders as failed rather than as a healthy partial answer.
