KruxApp Version 25.05.beta Android v0.2

First draft release of Krux App with a dedicated repository.
This is the first version of the app with KEF encryption format
The project structure was heavily modified.
Few tests were made, expect bugs.

Warning!
The app code is poorly tested and maintained. APK signatures and authorship are not yet managed. Users may need to delete older versions to be able to update, and it's very likely stored information, like settings and encrypted mnemonics will be lost on updates.
