question: 更新之后所有对话都报错

### 你想完成什么 / What are you trying to do

更新前是ok的，更新后只要对话就会触发：{"error":{"type":"invalid_request_error","code":"unsupported_feature","message":"Responses feature is not supported by the Chat Completions bridge: tools[34].web_search"}}

### 已尝试的步骤 / What you have tried

换过模型，重启等等基础方法都尝试，无法解决

### 环境 / Environment

- Cindy 版本或 commit / version or commit:
- 平台与版本 / platform & OS version:

Start by reproducing a conversation after the update and trace how the Responses feature is routed through the Chat Completions bridge, focusing on the tools[34].web_search error. Done means conversations no longer trigger the unsupported_feature error across the affected models.
