[bug] CLI hangs when outputting to clipboard under Wayland

[kekonn]

I used codesnap -f application.rb -o clipboard --has-breadcrumbs --has-line-number to generate a codesnap and it gets stuck on "Generating". When I replace -o clipboard with -o code.png it completes instantly. I imagine this is because clipboards under Wayland are complicated and have a completely different approach.

Turns out it doesn't actually hang. Of course the application has to stay open for the wayland clipboard content to stay available, but this isn't obvious when using the application.

Hey @kekonn, I just add a chapter to describe this issue on Wayland, you can refer to https://github.com/mistricky/CodeSnap?tab=readme-ov-file#linux-wayland

I have figured out the why in the mean time, I just think the prompt could be more helpful, but in my quick tinkering I haven't figured out how to make the spinner change from generating to something like: "Generating done, paste the image and close the program"
