Barrett Ruth 2776aaeb21 fix: correct Codeforces language version IDs and default to C++20 (#349) ... ## Problem `LANGUAGE_VERSIONS` mapped CF `c++17` to `89` (actually GNU G++20) and defaulted to `c++17`, which didn't match any CF entry. Helpdocs listed CF as having only `c++17`. ## Solution Fix CF version map to `c++17 → 54`, `c++20 → 89`, `c++23 → 91`, add `pypy3 → 70`. Change `DEFAULT_VERSIONS.cpp` to `c++20` (no behavioral change — `89` was already the submit default). Update helpdocs. Fix StyLua formatting in `race.lua`.		2026-03-06 19:01:55 -05:00
