The previous selectors were based on a hypothetical structure that does not
match the actual site. The real novelfire.net popular listing uses:
<li class="novel-item"> (not <div>)
<a href="/book/slug" title="Title">
<figure class="novel-cover"><img data-src="/path.jpg"></figure>
<h4 class="novel-title text2row">Title</h4>
</a>
</li>
And pagination uses <a rel="next"> (not <a class="next">).
Changes:
- ScrapeRanking: use li.novel-item, h4.novel-title, figure.novel-cover,
img[data-src]; strip base64 placeholder covers
- hasNextPageLink(): new helper walking all <a> nodes for rel="next"
- Import golang.org/x/net/html for Node.Attr access
- Test fixtures rewritten to match real structure (li/h4/rel=next)
- Status and genres removed from ranking items (not present on listing page)
Verified end-to-end: ranking.json written with 24 items on first fetch
