free-tv/iptv ? reverse-engineered prompt

Build me a simple project that keeps an up to date M3U playlist of free TV channels from around the world.

I want a clean way to organize channels by country, with one easy place to browse the available lists and a generated master playlist file I can open in any IPTV app. Please include support for a bunch of countries, and make it easy to add or update channels later without having to manually edit the final playlist every time.

If it helps, create a small script that builds the playlist from the country lists and keeps the output file in sync. I also want the repo to be straightforward for other people to contribute to, since this is meant to be a community maintained list.

Use current docs or examples online if you need to, and keep the result practical, simple, and ready to use.
