migrate `ucdjs-scripts` into the root scripts folder

[luxass]

I would like to move the ucdjs-scripts package into the scripts folder. The scripts folder will need to be added as a package.

So make the scripts into a package, that can be installed and handled. Migrate the existing ucdjs-scripts package into scripts.

Ensure that the behavior works as it does right now! After that, we should migrate away from CAC, we can utilize the parseFlags from node:util to remove CAC as a dependency.
