Comparing a larger model against a larger input size meant re-exporting at
resolutions other than the shipped 640, and the script only ever wrote that
one number. `IMGSZ` is now a second positional argument, defaulted to 640 so
every existing call is unchanged.
The experiment this was built for found bigger input a net loss on its own
merits — yolo26n-seg and yolo26s-seg at 1280 both lost track of large,
frame-filling subjects (a bus's box shrank and its score nearly halved)
in exchange for catching small or partially-occluded ones tiling already
handles. Nothing shipped from it, but the ability to re-run that comparison
is worth keeping.
