* fix(lib): close open redirect when in subrequest mode

Closes GHSA-cf57-c578-7jvv

Previously Anubis had an open redirect in subrequest auth mode due to an
insufficent fix in GHSA-jhjj-2g64-px7c. This patch adds additional
validation at several steps of the flow to prevent open redirects in
subrequest auth mode as well as implements automated testing to prevent
this from occuring in the future.

* docs: update CHANGELOG

Overview

Anubis is a Web AI Firewall Utility that weighs the soul of your connection using one or more challenges in order to protect upstream resources from scraper bots.

This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.

Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit "good bots" like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of "known good" bots to allow for a compromise between discoverability and uptime.

In most cases, you should not need this and can probably get by using Cloudflare to protect a given origin. However, for circumstances where you can't or won't use Cloudflare, Anubis is there for you.

If you want to try this out, visit the Anubis documentation site at anubis.techaro.lol.
