v0.10.1

更新内容

• 加固 Responses 原生探测：更稳健地判断上游是否支持原生 Responses API，避免误判导致不必要的降级或请求失败。
• 完善 Responses 请求的 fallback 处理：原生 Responses 调用失败时，更可靠地回退到 OpenAI Chat 路径。
• 修复工具历史（tool-history）相关错误：处理 Responses 请求中工具调用历史的序列化/回放异常，减少 4xx 失败。
• 同步 README 与使用说明书：补充 0.10.0 特性、配置选项与完整端点清单。

Changes

• Hardened the native Responses capability probe so upstream support is detected more reliably, avoiding misclassification that caused unnecessary fallback or failures.
• Improved fallback handling for Responses requests: native Responses failures now fall back to the OpenAI Chat path more reliably.
• Fixed tool-history related errors: handles serialization/replay anomalies in Responses tool-call history, reducing 4xx failures.
• Synced README and usage docs with 0.10.0 features, config options, and the full endpoint inventory.

验证 / Verification

• Full test suite: python -m pytest tests/ -q, 753 passed.
