v1.2.0

Changed

• Breaking: embed() and batch_embed() now return the full EmbeddingResponse instead of bare vectors, on both clients. Get the vectors via output() (one per input, so output()[0] for embed()), and token usage via usage() - previously usage on embedding calls was unrecoverable.
• Breaking: rerank() now returns the full RerankResponse instead of a list[RerankResult], on both clients. Get the sorted results via output() (or results), and token usage via usage().
• Breaking: EmbeddingResponse.output() now returns validated float vectors (list[list[float]]) and raises sthai.ResponseError for non-float encoding formats or when the response carries no embeddings. The raw entries stay available on data.
