Respect new folder structure for reuter.
Move variable initialization into section. Do not initialize if we
already can attach to a session.
Remove legacy database handling. Instead fetch customer name from file
path and concatenate project and customer to database name. This also
supports more deeply nested folder structure within customer folder.
Use writeShellApplication and adjust code to pass shellcheck.
Remove unnecessary overhead after migrating to writeShellApplication.
This involves binary paths as they are imported.
Also rename to custom-project to follow my naming scheme for custom
scripts.
No need for overlays.
Instead create own packages and call them via callPackage.
That will keep them simpler and allows dependency injection.
I can follow existing patterns from nixpkgs, etc.
