anutmagang/Free-HighQuality-Proxy-Socks ? reverse-engineered prompt

Build me a Python project that automatically collects and checks free proxy lists, then saves the working ones into simple text files I can use as raw links from GitHub.

I want it to pull from public proxy sources, test the proxies quickly with multiple threads, and only keep the ones that actually work with a good response time, around under 3 seconds. Please include HTTP, SOCKS4, and SOCKS5, and sort the results into separate files like all proxies, HTTP only, SOCKS5 only, and by country if possible, especially Indonesia and other common countries. If you can detect things like anonymous or elite proxies, that would be great too.

Set it up so the list can refresh automatically every 2 hours with GitHub Actions, and make sure the results get written back into the repo cleanly. If you need to look up current docs or a better way to do the automation, go ahead and do that.
