more eagerly discard constraints on overflow
We always discard the results of overflowing goals inside of the trait solver. We previously did so when instantiating the response in `evaluate_goal`. Canonicalizing results only to later discard them is also inefficient 🤷
It's simpler and nicer to debug to eagerly discard constraints inside of the query itself.
