Subject: [PATCH] feat(nix): add cachix binary cache to flake

Nix flake [schema] allows for a top level attribute called `nixConfig`.
This allows a flake to extend a users nix for the specific flake.

This lets us add ghostty's binary cache automatically when using the
repo (nix develop, nix build, ...).
