The Action Lint workflow pins its actions to commit SHAs but the repo had no dependabot.yml, so those pins had no automated freshness mechanism. Add weekly github-actions update coverage with a 3-day cooldown, and declare the matching dependabot-cooldown threshold in .github/zizmor.yml. Generated-By: claude-guard
