Merge pull request #70 from lsb11/fix/crawl-404s #26

	name: Edge freshness

	# WHY: from 25 Jul to 9 Oct 2026 public/_headers told Cloudflare's edge to
	# keep HTML for a year, and canonical URLs served content weeks older than
	# the deploy (scripts/lib/edge-freshness.mjs). Crawlers only fetch canonical
	# URLs, so a fix that deployed was not a fix crawlers could see. This asserts,
	# after each deploy and daily, that every sitemap URL serves the current bytes.
