Responses API

OpenAI Responses 协议，URL 路径 POST /v1/responses，供 Codex CLI 等客户端直连。


curl http://YOUR_HOST:8000/v1/responses \
  -H "Authorization: Bearer wk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/o3",
    "input": "Write hello world in Go"
  }'

流式响应透传上游原生事件序列，不会追加 [DONE] 标记。若返回 503 model_unavailable，说明该模型对应的上游通道未启用 responses 协议。
