Three fixes:
1. HTML parser completely rewritten with two-pass approach:
- Pass 1: regex finds each tag-type element and its full inner
content (up to closing </li|span|td|div>)
- Pass 2: within the content, extracts the tag name from the
tags=NAME URL parameter in the search link
The old single-pass regex captured the ? wiki-link (first <a>)
instead of the tag name (second <a>). The URL-param extraction
works on Rule34 (40 tags), Safebooru.org (47 tags), and
yande.re (3 tags). Gelbooru proper returns 0 (post page only
has ? links with no tags= param) which is correct — Gelbooru
uses the batch tag API instead.
2. prefetch_batch is now truly fire-and-forget:
gelbooru.py and moebooru.py use asyncio.create_task instead of
await for prefetch_batch. search() returns immediately. The
probe + batch/HTML fetch runs in the background. Previously
search() blocked on the probe, which made Rule34 searches take
5+ seconds (slow/broken Rule34 API response time).
3. Partial cache compose already fixed in the previous commit
complements this: posts with 49/50 cached tags now show all
available categories instead of nothing.
