post/domain-intel/v1/tech_detect1 credit

Tech-stack fingerprint from the homepage response headers + HTML: web server, CDN/WAF, and frameworks/CMS/analytics (WordPress, Next.js, Shopify, React, Bitrix, Tilda, Yandex.Metrica, …). Tries https, then plain http, then the www host, so HTTP-only and www-only-certificate sites are fingerprinted instead of reported as blocked; `https_available` tells you which it was.
