MortezaBashsiz/CFScanner ? reverse-engineered prompt

Build me a simple Cloudflare scanner tool that can check a large list of IPs and save the ones that actually respond through Cloudflare compatible setup.

I want it to be easy to run from the command line, with clear input and output files, and support the default connection style mentioned in the README, with an option to use my own vmess settings if I already have them. If it helps, you can include versions for the common platforms this repo mentions, but keep the main experience straightforward and ready to use.

Please make it practical, clean, and well organized, with sensible defaults, basic error handling, and clear instructions for how to run it. If you need current library or setup details, look them up online first.
