fix(www): replace stale benchmark route/sitemap counts with durable build-truth claim (#1312) (#1313)

* fix(www): replace stale benchmark route/sitemap counts with durable build-truth claim (#1312)

The benchmark page (en+zh) asserted '30 route modules, 205 sitemap URLs',
handwritten and stale since PR #1106 — the candidate build emits 146 sitemap
URLs across 150 pages from 34 route files, and the false claim shipped
verbatim in built HTML (verifier NO-GO F1).

Adjudication per derive-from-owned-truth: the counts add no benchmark value
(the page measures properties, not site scale) and cannot be derived into
Markdown without new injection machinery, so the volatile numbers are removed
in favor of a durable architectural property — every route prerendered, the
sitemap built from routes. No numeric claim remains to silently rot; en/zh
parity and locale availability stay under the existing www:check-truth and
content-graph gates, and the content-graph fingerprints are regenerated.

* style(www): deno fmt table padding on benchmark pages (#1312)

Root deno fmt re-pads markdown tables to cell width; my edited cells
changed the column widths. Content-graph fingerprints regenerated to
match the formatted sources.
