fix: normalize .md URLs to HTML equivalents during page discovery#44

llms.txt links use .md URLs (e.g. /docs/guide/index.md) while sitemaps use HTML URLs (e.g. /docs/guide/). Without normalization these appear as duplicate pages, and checks like page-size-html that expect HTML URLs silently fetch markdown content instead. Normalize .md URLs to their HTML form in extractLinksFromLlmsTxtFiles() and walkAggregateLinks() using the existing toHtmlUrl() helper. Markdown-specific checks are unaffected because they derive .md candidates from HTML URLs via toMdUrls().

Thanks for the PR, @mvvmm ! I note there are a few test failures, but they're logical results of the changes here. I'll merge and then rework or remove those tests. This should be a nice performance boost - I appreciate the work here!
