Updated version of 3.1, fixing some crashes observed in limited Google Play rollout. Also improved setup for building version without any Google Play dependencies for local LLMs. If everything is correct, there should be no traces of proprietary components in the app-release.apk which is supposed to be the main FOSS version of the app. I'm somewhat new to this, so if something is off let me know and we'll figure it out but I'm hopeful this should work for everyone.
