ci: cancel stale workflow runs per PR or ref Add workflow-level concurrency to the direct GitHub Actions entrypoints so a newer run for the same pull request or repository ref cancels the older in-progress run. Keep the reusable workflow graph, release guards, triggers, and permissions unchanged while documenting the concurrency policy and the official GitHub references used for the change. closes https://github.com/official-stockfish/Stockfish/pull/6773 No functional change.
