Subject: Clear $NIX_PATH

Ensure that $NIX_PATH is empty using a .envrc file. nix.dev considers references
to <nixpkgs>, <briefcase>, <depot>, <unstable> to be an anti-pattern because it
hinders reproducibility by introducing an implicit environment.

This repository is chock-full of references to
<{nixpkgs,unstable,briefcase,depot}>, so right now everything is broken.
