GPT-5 mini used very bad language.

### Describe the bug

"silently over-written"

### Affected version

Copilot v1.0.62

### Steps to reproduce the behavior

Ask if the untracked files overwrite the tracked files already pushed to the remote repo.

### Expected behavior

Give better information voluntarily. Do not push anything that would overwrite better, newer information. Use accurate words to describe things.

### Additional context

_No response_

报告中没有指出源文件或测试。通过询问未跟踪文件是否会覆盖推送到 remote repository 的已跟踪文件，在 Copilot v1.0.62 中复现该行为，然后定位响应生成路径及其覆盖情况。完成的标准是 CLI 提供准确且足够明确的信息，而不暗示发生了实际并未发生的覆盖。
