add multithreaded matetrack runs to CI Add runs with --threads 4 to our matetrack CI. These won't be deterministic, of course. But they may catch early some multithreading bugs in our mate reporting. Motivated by #6293 and #6296. https://github.com/official-stockfish/Stockfish/pull/6297 No functional change.
