Vercel AI SDK 为多提供商流式响应新增 interrupted 状态
原标题：@ai-sdk/xai@5.0.28
AI 摘要
Vercel AI SDK 发布 @ai-sdk/xai@5.0.28 补丁版本，当流在没有收到提供商完成信号就干净结束时，现在会报告 `interrupted` 状态，保留部分输出而不因中断单独报错。该变更覆盖 OpenAI、Anthropic、Google、Alibaba、Amazon Bedrock、Cohere、DeepSeek、Groq、Mistral、Moonshot AI、Perplexity、xAI 等多家提供商的流式接口。这是一项破坏性兼容变更，应用需在 finish-reason 分支中处理 `interrupted`；同时更新了 @ai-sdk/provider 与 provider-utils 依赖。
