`CloudFlare-Prefetch`

Cloudflare says it crawls a site when Prefetch URLs is enabled. The published user agent contains CloudFlare-Prefetch/0.1. The page does not say whether robots.txt controls this token. This check matches the whole token, so a group named CloudFlare-AlwaysOnline does not match, and it still reports the RFC 9309 decision.
