Version 7.1.0-dev.20260826.1

18 class ViaCall extends Base.extend() {}
~~~~~~~~~~~~~

Found 1 error in repro.js:18
```

### 🙂 Expected behavior

no error in TS7

### Additional information about the issue

_No response_

先从链接的复现用例及其 repro.js 示例开始，然后使用所引用的 TypeScript 7.1.0-dev 构建运行它，以确认 ViaCall 上的 TS8026 诊断。将 Base.extend() 继承情况与正常工作的 Base 标识符情况进行比较，并定位涉及的 JSDoc @extends 处理逻辑。当调用表达式情况不产生错误，同时现有行为保持不变时，即视为完成。
