 `llmapi` provides a typed `Client<Provider>` API for chat, streaming, embeddings, tool calls, and conversation persistence. The default config alias `Config` maps to OpenAI-style providers, so the common case does not need an explicit `openai::OpenAI` wrapper.

 `llmapi` 提供型別化的 `Client<Provider>` API，涵蓋聊天、串流輸出、embeddings、工具呼叫與對話持久化。預設別名 `Config` 對應 OpenAI 風格設定，常見情況下不需要顯式寫出 `openai::OpenAI(...)`。
