What is search_certificates_by_spki_sha256?

Searches certificates on https://crt.sh by SPKI SHA-256 fingerprint and parses the HTML results page into certificate records. Returns an empty items list when no certificates match. It runs on Notte's browser infrastructure and returns structured JSON, so you can call it like any other API — pass spki_sha256, timeout_seconds and get the result back without maintaining a scraper.
