Fix CI: refresh asset manifest, golden fixture, and format ordering

The previous commit shipped three stale artifacts that the CI verify
job catches and that I missed locally:

- src/asset_manifest.py held a HTML_CACHE_VERSION that did not match
  the embedded sources (the fingerprint step had not been re-run after
  the last embed). lint_seo_cache.py compares the two and fails when
  they drift; refreshed by make build.
- tests/fixtures/golden_examples.py was the pre-rewrite frozen
  catalog. It needs an intentional refresh after example rewrites; the
  five new pages and the cells added to existing pages were not yet
  reflected. Regenerated from load_examples() output.
- scripts/format_examples.py FRONTMATTER_ORDER did not list the new
  scope_first_pass key, so the eight broad-surface pages that took
  the scope-down shortcut were reported as misformatted. Added it
  between doc_path and see_also so the formatter has a stable slot.

The full local gauntlet now passes: embed-examples, fingerprint,
verify-examples (under Python 3.13), quality-checks, unittest (39),
ruff, lint_seo_cache, migration parity, format --check, git diff
--check.
