I kind of hate front derailleur clamps for just this reason, it's stupid-easy to over-tighten them and gouge the paint. First, it's probably just paint..I will be very surprised if you cranked on it hard enough to damage the tube. It's still a bummer on your nice frame but this is where it's good to lean into Grant's philosophy that the frame is the bike and the paint is a thing that kinda protects it and gets scratched.
For future efforts I would recommend going slow and only tightening until it seems fairly snug. I've found (to my surprise when I first learned it) that derailleurs stay stable without being super tight. But buddy I scratched a lot of paint before I learned this!
