file

给 DeepSeek Harness (DSH) Web 界面加一个 VS Code 风格的工作区文件浏览器：右侧文件树 + 可编辑标签页 + Markdown 阅读/编辑/分屏 + 悬浮大纲 + Quick Open 搜索。

把文件拖入/粘贴到 DeepSeek Harness Web：输入框原生引用气泡，随消息发送（含绝对路径），气泡渲染文件卡片。Drag/paste files into the DeepSeek Harness web GUI as native reference bubbles — absolute paths, file cards.

dsh-file-beam - DSH plugin: drag files into the web composer, resolve real absolute paths, hidden path injection for the agent (no copy, no path in composer).
