创建消息（Messages）

创建 Claude / Anthropic Messages 兼容请求（Claude Code 使用的形态），供 Claude 与 DeepSeek V4 使用，支持流式与非流式。其他模型请走 /v1/chat/completions。不属于这两个系列的模型同样会在调用任何模型之前被拒绝：400 invalid_request_error，消息为 model '<id>' must be called via /v1/chat/completions。错误体采用 Anthropic 信封 {"type":"error","error":{type,message,code},"request_id"}，不是其他端点的 OpenAI {"error":{…}} 形状。
