By having the `pp.proofs` feature use `⋯` when omitting proofs, when users copy/paste terms from the InfoView the elaborator can give an error message explaining why the term cannot be elaborated. Also adds `pp.proofs.threshold` option to allow users to pretty print shallow proof terms. By default, only atomic proof terms are pretty printed. This adjustment was suggested in PR #3201, which added `⋯` and the related `pp.deepTerms` option.
