allow use as a globally installable executable

One issue I ran into with dart_repl was that it's difficult to accommodate usage with dart pub global activate, especially in relation to scratchpad file paths. I suspect this package will run into the same issue when you get to the point of implementing a executable in your pubspec.

as for scratchpad, I use a temp directory and a blank package
