廠商中立串流同會話管理，唔依賴 UI。FetchChatProvider 用 POST + ReadableStream，composable 管訊息、狀態、重試、重新生成同中止。串流錯誤係 Error，唔經 Axios ApiError callback。

interface ChatProvider {
  chat(messages: readonly ChatMessage[], options?: ChatOptions): AsyncIterable<ChatChunk>;
}

ChatChunk: start / delta / error / finish. ChatOptions: signal?, conversationId?.

pnpm -F @vh5/ai-chat type-check
