This fixes the problem where some artifacts were not being cached when they should have been. The secret sauce is the `nix-store` command. Also stops emitting artifacts to GitLab. Automatic build scheduling via Nix is too convenient. Maybe I'll figure out a way to do both later on. Also pins the remaining unpinned dependencies, namely direnv and nix-direnv.
