feat(desktop): improve WorkHub floating interaction and progress

[M4n5ter]

English

Summary

WorkHub's shortcut could wait on settings and window navigation, and control calls brought an existing Desktop window to the foreground. Prewarm the floating surface, make shortcut presentation independent of pending navigation, and preserve the existing main window's focus and visibility during control.

• Show an inactive progress card with the current action and latest assistant text. Opening it restores the conversation; closing it dismisses progress for that turn without cancelling work. Returning to WorkHub from another view docks the conversation.
• Require a concise control status in the user's request language and display it once in tool activity. Keep recoverable technical errors in tool results and show localized failure copy to the user.
• Smooth floating-window resizing, slightly increase the conversation background opacity, and remove the redundant “Return to WorkHub” button above ordinary session composers; the sidebar remains the navigation entry.

Verification

• Desktop: 2,449 tests passed; UI: 426 passed; Runtime Host: 1,828 passed, 12 skipped.
• Three native WorkHub E2E tests passed on macOS, including renderer/draft preservation and background click, text input and trusted arrow-key delivery with no main-window focus event.
• Build, typecheck, lint, format, desktop/UI Knip, renderer architecture, E2E budget and ASF header checks passed locally.
• Verified progress-card appearance with ordinary Electron background throttling, and an actual control turn opening Extensions while the main window stayed unfocused. Windows native behavior has not been verified locally.

概要

WorkHub 快捷键此前可能等待设置读取和窗口导航，control 调用也会把已有 Desktop 主窗口拉到前台。现在预热悬浮界面，让快捷键展示不再等待未完成的导航，并在控制期间保留已有主窗口的焦点和可见状态。

• 新增不抢焦点的进度卡片，展示当前操作与最新助手文字。打开卡片可查看对话；关闭只隐藏本轮进度，不取消任务。从其他页面返回 WorkHub 时自动收回对话。
• control 必须提供使用当前用户请求语言的简短状态，并在工具活动中只显示一次。可恢复的技术错误保留在工具结果中，用户界面显示本地化失败提示。
• 改善悬浮窗缩放动画，略微提高对话底色不透明度，并删除普通会话输入框上方重复的“返回 WorkHub”按钮；保留侧栏导航入口。

验证

• Desktop：2,449 项测试通过；UI：426 项通过；Runtime Host：1,828 项通过、12 项跳过。
• macOS 上 3 项 WorkHub 原生窗口 E2E 通过，涵盖 renderer／草稿保留，以及后台点击、输入文字和可信方向键事件；主窗口没有收到焦点事件。
• 本地构建、类型检查、lint、格式、Desktop／UI Knip、renderer 架构、E2E 预算和 ASF 文件头检查通过。
• 在 Electron 正常后台节流条件下验证进度卡片显示，并通过实际 control 对话打开扩展页面，确认主窗口保持失焦。尚未在 Windows 实机验证原生窗口行为。

新增进度卡片截图，来自原生窗口，使用示例状态和文字：
