feat(frontend): 侧边栏紧凑化与挤压式重设计，移除工作区面板功能拆分

- 对话侧边栏：行高/字号/圆角紧凑化，fixed 覆盖式改为文档流挤压式展开，移除工作区/虚拟显示器按钮
- 新增 WorkspaceSwitcher 浮层组件：列表即切换器，内联重命名/删除确认/新建表单动画，「…」菜单 fixed 逃逸裁切，刚好 7 行内部滚动
- 移除 LeftPanel 及两个旧工作区对话框：管理工作区迁入侧边栏，文件管理迁入输入栏 + 菜单（最多 4 项滚动）
- 个人空间移除默认隐藏工作区/隐藏快捷窗口设置项；删除 panelMode 门控轮询（QuickDock 常驻轮询 + socket 推送替代）
- 修复 flex 压缩导致菜单行高失效、分组对话 viewport 裁切最后一行、action-wrap 撑高对话项、/new 残留最近对话待办（无对话 id 不再请求 todo-list）
- 工作区入口按钮改内联 layers 图标并统一 18px，host/docker 模式 localStorage 缓存避免按钮首屏延迟出现

+      <h2>设计决策</h2>
+      <ul>
+        <li><b>入口合并</b>：侧边栏新增「工作区」入口（行尾常显当前工作区名），替代原「工作区 / 虚拟显示器」按钮与左侧面板里的管理入口。</li>
+        <li><b>列表即切换器</b>：工作区行是可选项，单击整行切换；当前行用中性底色标识。</li>
+        <li><b>管理动作收拢</b>：设为默认 / 重命名 / 在文件夹中打开 / 删除收进每行 hover 的「…」菜单；菜单用 fixed 浮层定位（同个人空间二级菜单），不被浮层裁切。</li>
+        <li><b>在文件夹中打开</b>：复用输入栏 git 状态区的现成能力，仅宿主机模式可用，Docker 模式下禁用。</li>
+        <li><b>全内联操作</b>：新建 / 重命名 / 删除确认都在浮层内联完成；新建区域带高度展开动画。</li>
+        <li><b>反套娃</b>：单层扁平容器 + 细发丝分隔线；行内不再出现任何边框卡片。</li>
+        <li><b>对齐</b>：行结构统一；名称 13px / 路径 12px 单行截断；图标与首行文字视觉对齐。</li>
+        <li><b>token 化</b>：颜色全部走三主题语义 token，hover / 选中用中性灰，accent 仅用于「创建」CTA。</li>
+      </ul>
+      <h2>模式差异</h2>
+      <ul class="notes-compare">
+        <li>宿主机模式：显示路径行，菜单含「在文件夹中打开」。</li>
+        <li>Docker 模式：叫「项目」，不显示路径，「在文件夹中打开」禁用，新建只需名称。</li>
