feat(flake): complete revamp with devenv/direnv
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. For more information see: https://devenv.sh NOTE: impure is used only because of the devenv-managed state, do not be alarmed!
