Detect bots from HTTP_FROM

I think this should be implemented, and I have three reasons for this:

1. User agents change and it's hard to keep up will all bots, worldwide, especially if they don't get reported so we can add them, and also we can detect them right away.
2. Bing uses Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/130.0.0.0 Safari/537.36 Edg/130.0.0.0 and HTTP_FROM is bingbot(at)microsoft.com.
3. Bots are required to send HTTP_FROM https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/From

If HTTP_FROM is detected then it should be treated as generic bot, then further check for specific bot name.

No files, tests, or code entry points are named. Start by tracing the existing bot-detection path and how request headers and user-agent strings are handled, then determine where HTTP_FROM should trigger generic bot detection and where the listed addresses should identify specific bots. Done means the proposed cases are covered without relying only on changing user-agent strings.
