feat: Android AM Intent interface

[izelnakri]

Hi there,

I've read the other NixOS issue and found this project inspiring. It definitely needs a nix flake interface along with the CLI & TUI and that won't be too much code. Feedback I provided on a related channel:

"It would be better to expose these as nix flakes as well. I can see Android AOSP providing something similar via Activity Manager Intents as well even in ~5 years. This might be better than TaskerNet feature of the Tasker android app. I'll forward my feedback to Chris as a GitHub issue :P"

Thanks again for building this inspiring project!

About nix: see #759 (comment) & #765. We think creating a flake for nix would be pointless as there's not much you can do with Linutil on NixOS without adding support to every script.
