Verify the installer script's SHA256 hash against pinned values before execution, closing a supply chain gap. The expected hashes are stored in .codspeed-runner-installer-hashes.json (sourced from GitHub API digests). - For pinned release versions: download to temp file, verify hash, fail on mismatch or missing hash - For latest/branch/rev: warn that hash verification is not available - Add `skip-hash-check` input to bypass verification if needed - Update bump-runner-version workflow to fetch and store the hash Ref: COD-2243
