Adds the slugs that hadn't been captured in the first batch (some
extra coverage from a later examples-* file, plus 10 retries that
hit a transient waitForLoadState timeout on the first sweep).
Coverage is now 129/129 — every example exposed via sitemap.xml has
a real canvas screenshot. The few that still 404 (slugs only present
in non-sitemap data files) keep the CircuitPreview fallback.
