Feat: Let search engines crawl free. and raise the burst limit to ~20 req/10s

Browse Source 
free.* now serves a robots.txt that allows everything, so free images embedded in
pages (e.g. apophenia.news articles) can be indexed and used for previews. The
main site and ai.* keep the homepage-only robots.txt. The WAF rate limit rule is
now 20 req/10s and skips known bots.

- `i` above `20` serves `max-i.webp`, which lists each site's range. Other invalid values serve `bad.webp`
- Only free images are served: if there's no image (or fewer than `i` working ones), `bad.webp` is served (remembered for 24h) instead of an AI image. With a `src`, only that source's images are searched
- Each `src` + `i` + query combination is cached separately. Like the main site, other `i` values within an hour of a search reuse its results and don't count as searches
- Search engines may crawl `free.` (its robots.txt allows everything), so free images embedded in your pages can show up in image search and link previews. The main site and `ai.` allow only the homepage
