Nix integration

[Jack5079]

So I can actually use it y'know

It's next to impossible to reproduce installation of existing Fediverse servers. I tried Akkoma, Mastodon, and Calckey in an Azure (Ubuntu) VM (and remade the VM after each failure) and none worked.

As well I switched to NixOS a week ago so I should probably have this setup to avoid fucking up state

Python has seemingly better Nix integration than JavaScript at the cost of being 20x slower, as well as being harder to learn or use than JavaScript

Nix can't use pnpm-lock.yaml but it can use package-lock.json, weird
