ci: pin root workflow actions to immutable SHAs Pin every external action used by the root GitHub workflow set to a full-length commit SHA and keep the selected release tag as a same-line comment. Update the root workflows to the latest stable tagged action versions found during the audit while preserving existing release guards, permissions, and reusable workflow wiring. closes https://github.com/official-stockfish/Stockfish/pull/6754 No functional change.
