[feature] Support btop

[btop](https://github.com/aristocratos/btop ) is a very beautiful and powerful tool as htop. It works fine on some terminal emulators as "termius" which will fullscreen it but on windterm it seems to be not so compatible with the buffer and the scrollbar will ruin the screen. I do not know much about the cause but I guess it has something to do with the buffer mode of windterm since windterm will keep the scroll bar that could trace back to the history input before launching those program supposed to be fully possesed the screen, e.g. ` vim anyfile ` . This will not be a problem when using vim but it is a problem when using some applications like btop. Could you consider add support for these kind of applications?

Start by reproducing the btop display problem in WindTerm and compare it with vim, which the issue reports as working correctly. Investigate how fullscreen terminal applications interact with the buffer and scrollbar; done means btop renders without the scrollbar corrupting the screen.
