Refactor and split out things into cmd and lib (#77)

* Refactor anubis to split business logic into a lib, and cmd to just be direct usage. * Post-rebase fixes. * Update changelog, remove unnecessary one. * lib: refactor this This is mostly based on my personal preferences for how Go code should be laid out. I'm not sold on the package name "lib" (I'd call it anubis but that would stutter), but people are probably gonna import it as libanubis so it's likely fine. Packages have been "flattened" to centralize implementation with area of concern. This goes against the Java-esque style that many people like, but I think this helps make things simple. Most notably: the dnsbl client (which is a hack) is an internal package until it's made more generic. Then it can be made external. I also fixed the logic such that `go generate` works and rebased on main. * internal/test: run tests iff npx exists and DONT_USE_NETWORK is not set Signed-off-by: Xe Iaso <me@xeiaso.net> * internal/test: install deps Signed-off-by: Xe Iaso <me@xeiaso.net> * .github/workflows: verbose go tests? Signed-off-by: Xe Iaso <me@xeiaso.net> * internal/test: sleep 2 Signed-off-by: Xe Iaso <me@xeiaso.net> * internal/test: nix this test so CI works Signed-off-by: Xe Iaso <me@xeiaso.net> * internal/test: warmup per browser? Signed-off-by: Xe Iaso <me@xeiaso.net> * internal/test: disable for now :( Signed-off-by: Xe Iaso <me@xeiaso.net> * lib/anubis: do not apply bot rules if address check fails Closes #83 --------- Signed-off-by: Xe Iaso <me@xeiaso.net> Co-authored-by: Xe Iaso <me@xeiaso.net>

+			<summary>Why am I seeing this?</summary>
+			<p>You are seeing this because the administrator of this website has set up <a href="https://github.com/TecharoHQ/anubis">Anubis</a> to protect the server against the scourge of <a href="https://thelibre.news/foss-infrastructure-is-under-attack-by-ai-companies/">AI companies aggressively scraping websites</a>. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.</p>
+			<p>Anubis is a compromise. Anubis uses a <a href="https://anubis.techaro.lol/docs/design/why-proof-of-work">Proof-of-Work</a> scheme in the vein of <a href="https://en.wikipedia.org/wiki/Hashcash">Hashcash</a>, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.</p>
+			<p>Ultimately, this is a hack whose real purpose is to give a "good enough" placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.</p>
+			<p>Please note that Anubis requires the use of modern JavaScript features that plugins like <a href="https://jshelter.org/">JShelter</a> will disable. Please disable JShelter or other such plugins for this domain.</p>
+		</details>
+		<noscript>
+			<p>
+				Sadly, you must enable JavaScript to get past this challenge. This is required because AI companies have changed
+				the social contract around how website hosting works. A no-JS solution is a work-in-progress.

This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.</p><p>Anubis is a compromise. Anubis uses a <a href=\"https://anubis.techaro.lol/docs/design/why-proof-of-work\">Proof-of-Work</a> scheme in the vein of <a href=\"https://en.wikipedia.org/wiki/Hashcash\">Hashcash</a>, a proposed proof-of-work scheme for reducing email spam. The idea is that at individual scales the additional load is ignorable, but at mass scraper levels it adds up and makes scraping much more expensive.</p><p>Ultimately, this is a hack whose real purpose is to give a \"good enough\" placeholder solution so that more time can be spent on fingerprinting and identifying headless browsers (EG: via how they do font rendering) so that the challenge proof of work page doesn't need to be presented to users that are much more likely to be legitimate.</p><p>Please note that Anubis requires the use of modern JavaScript features that plugins like <a href=\"https://jshelter.org/\">JShelter</a> will disable. Please disable JShelter or other such plugins for this domain.</p></details><noscript><p>Sadly, you must enable JavaScript to get past this challenge.
