问题
切换语言后，浏览器页签标题不会跟随更新，仍显示旧语言的标题文本。
解决方案
1.
router/title.ts— 新增titleKey参数resolveDocumentTitle()新增可选参数titleKey，优先通过 i18n 翻译生成标题，翻译失败时回退到静态routeTitle。2.
router/index.ts— 传入路由 meta.titleKeybeforeEach守卫调用resolveDocumentTitle时，将路由meta.titleKey一并传入，使导航时的标题即可国际化。3.
i18n/index.ts— setLocale 后同步刷新标题setLocale()完成语言切换后，读取当前路由的meta.titleKey并重新调用resolveDocumentTitle，更新document.title，确保页签标题与 UI 语言保持一致。测试
