fix(agent/setup): Fix revising constraints and best practices (#6777)

In a `for item in list` loop, removing items from the list while iterating causes it to skip over the next item. Fix: refactor `interactively_revise_ai_settings` routine to use while loop for iterating over constraints, resources, and best practices.
