Insert the `performance-audit` composite action from `jabranr/workflows` as a step that runs Lighthouse against one or more URLs and posts results to PRs or uploads them as artifacts (step-level `uses:`). Load when the user asks to add Lighthouse to CI, run performance audits, audit Core Web Vitals on PRs, or wire `jabranr/workflows` performance-audit. Do not load for creating a new top-level workflow file.
