Description
Is your feature request related to a problem? Please describe.
Coming from Capture One, where I've developed an easy way to cull photos by comparing all of them (up to 12 at a time), deselecting the sharpest image, and flagging the rest for deletion, i've struggled to replicate it in Darktable. I can compare images (albeit a bit slower to select) but I cannot pixel peep as easily, seeing as zooming is forcefully disabled over 4 images.
Describe the solution you'd like
Increasing the limit for the culling mode zoom.
Alternatives
Currently I'm importing my photos through Capture one, then switching back to my linux install, it works, but i'd rather I didn't have to. If there's something I've missed, let me know
Additional context
This is how easy it is for me to compare for culling on capture one:

Research direction
Start by locating the darktable culling mode entry point and the code that enforces the four-image zoom limit. Check how zoom is currently disabled when more than four images are selected and determine a safe higher limit for modern systems. Done means culling mode permits the requested expanded zoom comparison without breaking selection or display behavior.
