Summary

SDK initialization on Vercel cold starts is ~7x faster (p75 from >70 ms to 10 ms) by loading the bundled flags datafile upfront and checking revisions locally.
Usage reporting no longer uses waitUntil, so it no longer prolongs function execution after the response.
Update to @flags-sdk/vercel v1.5.3 or later and redeploy.
