Codeforces github sync per prze8969

CF → GitHub Sync watches your Codeforces submissions and automatically
pushes every Accepted solution to a GitHub repository of your choice.

Each solve gets saved as:
- codeforces/{contest}/{problem}/solution.{ext} — your actual source code
- codeforces/{contest}/{problem}/notes.md — a pre-filled stub with the
problem link, tags, rating, and language, with blank sections for your
approach, mistakes, and complexity so you can write it up later

No more manually copying code after every contest — solve on Codeforces,
and your GitHub streak and problem archive build themselves.

Setup: add your Codeforces handle and a GitHub personal access token in
the extension's settings, pick your repo, and it starts syncing in the
background on a timer you control.

Note: this requires you to be logged into Codeforces in Firefox, since it
reads submission source from your logged-in session.
