Raise ValueError in add_argument() if either explicit nargs=0 or action that does not consume arguments (like 'store_const' or 'store_true') is specified for positional argument.

Overall, LGTM. I had one comment about whether we could be more actionable in the error message, but there may be existing style guidance around error messages that I don't know about, which makes my comment moot.

Thank you for your review @savannahostrowski. I think that the error messages are in line with existing error messages and do not need to be too verbose. This is a task for documentation.
