StructuredOutputPart — a typed structured response attached to the assistant message that produced it. Generic over the schema-inferred data type so consumers can thread useChat({ outputSchema })'s schema all the way down to messages[i].parts[j].data. Defaults to unknown so untyped consumers (e.g. internal codepaths that don't know about TSchema) keep working.

Discriminated on status: checking status === 'complete' narrows data to TData.
