[Feature Request] Add verbosity control for Claude response output

Bug Description
Why would max effort (my default mode) suddenly become max verbosity? The more words there are, the less meaning they carry. Claude Opus 4.7 in default mode is a stupid blabber, if compared to Opus 4.6 when max reasoning is on. A good thinker expresses thoughts in a more concise manner, when compared to someone who doesn't think through as much. Please allow me to regulate verbosity (or at least don't force it on me), or else I feel I am forced to turn Claude into a Caveman. This word diarrhea is intolerable.
