WebContents。chrome::CanDuplicateTabAt还会拒绝正在显示 interstitial 或没有最后提交导航条目的标签页。此时菜单仍可用，但dao::DuplicateActiveTab返回失败，执行路径仍返回true，因此命令无操作。使用浏览器和当前活动索引调用chrome::CanDuplicateTabAt作为菜单与执行路径共用的可用性条件。🤖 Prompt for AI Agents

使用本地化资源断言 FillInput 的结果。
VKEY_TAB 和 VKEY_RIGHT 会将 GetCommandTitle() 的本地化结果传给 FillInput()，后者再添加 u"> "。当前英文字面量会在非英文资源下产生错误失败，并且无法覆盖本地化输入行为。请改用对应的字符串资源。

Background
The command bar needed quick browser actions so users can open common browser pages or run simple actions without leaving the keyboard.
Changes
>command mode behind a new settings toggle, while keeping normal command suggestions available.Testing
Patch includes browser tests for system command behavior and settings WebUI tests for the new toggle. Documented evidence says
npm run rebuild,git diff --check, resource checks, identifier checks, and documentation checks passed; the new browser tests remain uncompiled and unrun because the available test binary was stale.Summary by CodeRabbit
New Features
>prefix, with localized aliases and keyboard navigation.Improvements
