Subject: [PATCH] chore(harness): add actions/stale workflow to auto-close
 inactive issues and PRs

Add GitHub's maintained actions/stale action on a daily schedule. Issues and pull requests inactive for 14 days are marked stale with a comment, then closed 7 days later if still untouched; any comment, commit, or label change resets the clock. help wanted and good first issue labels are exempt, and draft PRs are never marked stale.
