Merge branch 'master' into feat/workbench-saas-polish-and-reset

本次提交包含以下改进：

## 1. Workbench视图重置机制 (App.tsx + WorkbenchPage.tsx)
- 在App.tsx中新增workbenchResetToken状态，每次导航到workbench页面且存在session时递增token
- WorkbenchPage新增resetToken属性，检测token变化后自动调用handleNewConversation()重置工作台状态
- 重置时清空消息列表和活跃会话ID，确保每次进入工作台都是全新状态

## 2. 滚动操作提示系统 (WorkbenchPage.tsx)
- 新增scrollActionHint状态和hideScrollActionHint/showScrollActionHint方法
- 用户滚动离开消息区域时自动显示滚动方向提示（顶部/底部按钮）
- 1.4秒后自动隐藏提示，优化交互体验
- 手动点击滚动按钮后立即隐藏提示
- 为滚动按钮添加--top/--bottom标识类名，支持独立定位

## 3. Prompt案例弹窗自适应布局 (WorkbenchPage.tsx)
- renderPromptCaseOverlay重构为动态计算moda l类名
- 根据图片实测宽高比(is-tall-media/is-portrait-media)和文案长度(is-long-copy)动态调整布局
- 添加handlePromptCaseImageLoad回调在图片加载后测量尺寸

## 4. Workbench SaaS视觉美化 (workbench.css)
- 全新SaaS风格设计变量(--wb-panel, --wb-line, --wb-shadow等)
- 首页区域：标题样式、Composer输入框圆角/阴影/聚焦态、发送按钮渐变样式
- 模式选择/芯片组件：下拉菜单、悬停态优化、选中态高亮
- 聊天消息区：气泡圆角、头像样式、消息间距、空状态引导
- 图片/视频结果卡片：边框、阴影、标签徽章、视频PLAY标识
- 生成中卡片：停止按钮样式
- 会话侧边栏：折叠态浮动按钮定位、展开态面板样式、选中项左侧指示条
- 滚动快捷键：固定定位圆形按钮、显示/隐藏过渡动画
- Prompt案例弹窗：桌面端毛玻璃双栏布局、移动端底部面板布局
- @media适配：560px/720px/900px/980px四个断点全覆盖

## 5. 全局移动端布局变量 (dark-green.css)
- 新增--dg-mobile-nav-height/gap/space CSS变量，统一移动端底部导航高度计算
- 优化Topbar z-index层级
- 非特殊页面自动添加顶部padding避让移动导航
- Profile弹窗fixed定位及安全区域适配
