A common workflow is to have a local .envrc, allow contributors to do
so. Still provide the recommended Nix-based setup, for those who wish to
use it.
That file can then be copied to or symlinked to `.envrc`.
Use path as an input that can be overriden automatically when direnv is
in use.
nix-direnv version present in .envrc has been updated, using watch_file on the flake is already handled.
Not perfect, and mostly a port of the previous edition. Hours have
already been sunk into this, and need to get this out for consumption,
and for ironing out.

NOTE: impure is used only because of the devenv-managed state, do not be
alarmed!
