refactor/bring data collections back home

[blaggacao]

• refactor: bring back config data sets
• refactor: use local config data sets
• refactor: normalize configs
• test: review and accept new lib.cfg snapshot

Context

Previously, the nixago data collections where factored out in an attempt to be more crisp.

This attempt completely failed and it was just absolutely unergonomic to use divnix/std-data-collection whereas the stated aim of Standard is to reduce the setup time and get you up-and-running quickly.

Solution

Incorporate the config data once again into the repository. Be opinionated on purpose. Get people up and running quickly.
