Generate short-lived, mobile-friendly ngrok preview links for local artifacts and share them in Telegram. Use when OpenClaw produces images/charts/generated files that the user needs to view remotely on phone, and a temporary per-task link is preferred over manual file transfer.

为本地生成的文件创建短期有效的、适合移动设备的ngrok预览链接，并通过Telegram分享。适用于OpenClaw生成图片、图表或输出文件，用户需在手机远程查看，且偏好使用临时任务链接而非手动传输文件。
