Klein Edit Composite Node–Sidestep Pixel/Color Shift, Limit Degradation

Seems like a few people found this useful, so I figured I'd make a regular post. Claude and I made this to deal with Klein's color/pixel shifting, though there's no reason it wouldn't work with other edit models. This node attempts to detect edits made, create a mask, and composite just the edit back on to the original, allowing you to go back and make multiple edits without the fast degradation you get feeding whole edits back into Klein. It does not really fix the issues with the model, of a band-aid really. I'd say this is for "static" edits, big swings/camera moves will break it.
