修复了writeBackID函数

修复完成！

现在我已经修复了 [writeBackId](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 函数，新的逻辑如下：

修复内容

1. 空 [id:](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 行现在会被填充：之前只要发现 [id:](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 就跳过，现在会检查该行的值
2. 三种情况处理：
   • 没有 [id](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 行 → 新增 [id: <数字>](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
   • 有 [id:](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 但为空 → 替换为 [id: <数字>](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)
   • 有 [id: <已存在数字>](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) → 保持不变

测试新逻辑

你可以重新发布那个有空 [id:](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html) 行的文章来测试：

预期结果

发布成功后，你的 posts\aaa.md.md 文件顶部应该从：

变成：

（其中 1234 是 WordPress 返回的实际文章 ID）

调试信息

如果开启了 [DEBUG_PUBLISH=1](vscode-file://vscode-app/c:/Users/wingxu/AppData/Local/Programs/Microsoft VS Code/resources/app/out/vs/code/electron-browser/workbench/workbench.html)，你会看到类似这样的输出：

现在再试一次发布，空 ID 应该会被正确写回了！
