PR https://github.com/TecharoHQ/anubis/pull/1015 added the ability for
reverse proxies using Anubis in subrequest auth mode to look at the path
of a request as there are many rules in the wild that rely on checking
the path. This is how access to things like robots.txt or anything in the
.well-known directory is unaffected by Anubis.
However this logic was also enabled for non-subrequest deployments of Anubis,
meaning that a specially crafted request could include a /.well-known/
path in it and then get around Anubis with little effort.
This fix gates the logic behind a new plumbed variable named subrequestMode
that only fires when Anubis is running in subrequest auth mode. This
properly contains that workaround so that the logic does not fire in
most deployments.

Using the User-Agent as a filtering vector for the honeypot maze was a
decent idea, however in practice it can become a DoS vector by a
malicious client adding a lot of points to Google Chrome's User-Agent
string. In practice it also seems that the worst offenders use vanilla
Google Chrome User-Agent strings as well, meaning that this backfires
horribly.
Gotta crack a few eggs to make omlettes.
Closes: #1580

* feat: first implementation of honeypot logic
This is a bit of an experiment, stick with me.
The core idea here is that badly written crawlers are that: badly
written. They look for anything that contains `<a href="whatever" />`
tags and will blindly use those values to recurse. This takes advantage
of that by hiding a link in a `<script>` tag like this:
```html
<script type="ignore"><a href="/bots-only">Don't click</a></script>
```
Browsers will ignore it because they have no handler for the "ignore"
script type.
This current draft is very unoptimized (it takes like 7 seconds to
generate a page on my tower), however switching spintax libraries will
make this much faster.
The hope is to make this pluggable with WebAssembly such that we force
administrators to choose a storage method. First we crawl before we
walk.
The AI involvement in this commit is limited to the spintax in
affirmations.txt, spintext.txt, and titles.txt. This generates a bunch
of "pseudoprofound bullshit" like the following:
> This Restoration to Balance & Alignment
>
> There's a moment when creators are being called to realize that the work
> can't be reduced to results, but about energy. We don't innovate products
> by pushing harder, we do it by holding the vision. Because momentum can't
> be forced, it unfolds over time when culture are moving in the same
> direction. We're being invited into a paradigm shift in how we think
> about innovation. [...]
This is intended to "look" like normal article text. As this is a first
draft, this sucks and will be improved upon.

* feat(lib): use new challenge creation flow
Previously Anubis constructed challenge strings from request metadata.
This was a good idea in spirit, but has turned out to be a very bad idea
in practice. This new flow reuses the Store facility to dynamically
create challenge values with completely random data.
This is a fairly big rewrite of how Anubis processes challenges. Right
now it defaults to using the in-memory storage backend, but on-disk
(boltdb) and valkey-based adaptors will come soon.
