/**
 * 嵌入模式 Web 控制器（`TencentQianWebViewController`）单测。
 *
 * 控制器是「宿主 ↔ 组件内部 WebView 命令」的解耦载体，纯逻辑、无 ArkUI / WebView 依赖，
 * 覆盖三条契约：
 * 1. 未 attach（组件尚未挂载）时全部命令安全 no-op，`canGoBack`/`handleBack` 返回 false；
 * 2. attach 后命令如实转发到组件注入的实现（含 `handleBack` 的组合语义）；
 * 3. detach（组件销毁）后复位为 no-op，防止宿主误调用触及已销毁的 WebView（野引用防护）。
