Support for other webviews

[iCaran]

Setter simply crashes if i select Vanadium Webview, I haven't tried any other webviews, but I think Setter would behave same with them.

Android 14
LineageOS

I have a pixel 7/Graphene with Varadium built-in and a Oneplus/LineageOS with Mulch as system webview, all running smooth. Can you try Mulch?
