proxyscrape/free-proxy-list ? reverse-engineered prompt

Build me a public GitHub repo that acts like a live mirror of a free proxy list.

I want it to keep a current list of HTTP, HTTPS, SOCKS4, and SOCKS5 proxies, refreshed automatically every 5 minutes, and published as plain text, JSON, and CSV. The data should include useful details like IP, port, country, city, anonymity, SSL support, uptime, latency, ASN, ISP, and when it was last checked. Please organize it so people can grab all proxies at once, or filter by protocol and by country, with separate folders for each shard.

Make the README clear and friendly, with quick examples showing how to download the latest files from the repo or CDN. Add the badges and basic stats section too, and make empty lists return a sensible not found result instead of stale data. If you need to check current docs or best practices for the update flow, look them up online first.
