Share images, screenshots, and files from the AI workspace to users on the local network via HTTP. Use when the agent needs to show images, browser screenshots, or any files to the user and the current channel doesn't support inline media (e.g., webchat, CLI). Starts a lightweight Node.js static file server on LAN, managed by systemd. Drop files in the shared directory and send the user a clickable URL.

通过HTTP将AI工作区中的图片、截图和文件共享给局域网内的用户。当代理需要向用户展示图片、浏览器截图或任何文件，而当前通道不支持内联媒体（如网页聊天或命令行界面）时使用。在局域网内启动一个轻量级Node.js静态文件服务器，并由systemd管理。将文件放入共享目录后，向用户发送可点击的URL链接。
