I don't think you have to or should stress in your CV that you intend to go back and do a PhD.

From a recruiter's point of view being a PhD dropout might be even better because it could mean that you won't go back and you will stay being productive where they hired you after they invest in training you the first couple of months/a year.

I'd leave it open ended. In practice, it's just your plan, it's not a given, it can change based on many things. If they ask you, you can explain that it wasn't a good match and that you may or may not try again but right now you want industry experience. You could sell it as wanting to do practical, useful, not ivory tower things which could possibly in the longer term give you a better idea what would be worthwhile research if you ever decide to go back.
