What is the proper way to store user settings?

Excellent library, thank you @simonw

I have several workflows built on llm, but I use nix home manager, which means I try to be declarative about my tool settings.

What's the best way to store llm configs via dotfiles or declaratively? Specifically, I'd like to store plugins, default model choices, and other config. Likely the SQLite db as well.
