创建备用域名请求失败

Error message

创建备用域名请求失败: %w

What it means

Fallback-path error in PanwikiPlugin.searchPage (plugin/panwiki/panwiki.go:187): after the primary domain request failed, the client was switched to the backup domain, but constructing the retry request for the backup domain failed. The domain switch happened; the rebuild itself is what broke.

Solutions

1. 校验 BackupBaseURL 常量格式
2. 对备用 URL 做预检验证
3. 域名切换失败时回退返回原始错误
