Split distro to generic module and deployment stuff

Now Pheix includes everything you needed for deployment: generic module, start up script, web resources, configuration files, etc...

The goal is to split up a distributive to:

1. Pheix raku module as the generic entity;
2. Pheix deployment stuff as the dependency or addon;
3. ✅ Pheix test suite as the Trove module: https://github.com/pheix/raku-trove;
