[Feature] Nanobrowser Integration of features

[sgtest2026-ux]

Feature Description / 功能描述

I generally use NanoBrowser to log in to a webpage and then click through all the menus one by one, but there hasn't been any development on NanoBrowser for a long time. When I checked out this project, it's really nice, and I think it would be even better if NanoBrowser features were added to it.
