IndexNow integration is live for Bing and Yandex

We added IndexNow — the open protocol used by Bing, Yandex, Seznam, and Naver for real-time indexing. A GitHub Action now fires on every content push: 60-second wait for Vercel to deploy, then all sitemap URLs are posted to the IndexNow endpoint. Our first submission pushed 1,117 URLs to all four search engines. Google doesn't participate in IndexNow; we submit its sitemap via Search Console separately.
