Discover multi-page scans from XML sitemaps

[LyraZeta]

Problem

Applications with several routes currently require users to enumerate each --path. Most production sites already publish a sitemap that can provide a deterministic route list.

Proposed scope

• Add --sitemap <url-or-path> for XML sitemaps and sitemap indexes.
• Resolve same-origin URLs only by default.
• Add --sitemap-limit and include/exclude glob filters.
• Deduplicate routes while preserving stable report order.
• Surface skipped or invalid entries in terminal output without failing the entire scan.

Acceptance criteria

• Unit fixtures cover a sitemap, a sitemap index, duplicates, and external URLs.
• The scanner produces stable routes and artifact names across runs.
• Documentation includes one local and one deployed-site example.
