feat(web): real /about and /docs pages (unique crawlable content)

Addresses the top cross-engine AEO finding — every route previously served
the homepage SPA. /about and /docs are now distinct routes with their own
server-rendered content and titles.

- /about: substantive about page (what LogicSRC is, the standards surface,
  CommandBoard.run reference impl, GitHub, hire-us) — derived from public
  positioning, no fabricated team.
- /docs + /docs/[slug]: render the repo's docs/*.md (curated public set) via
  marked, statically generated at build (no runtime fs dependency).
- Drop about/docs from the catch-all; add doc URLs to the sitemap.

Verified in a running build: /about and /docs serve unique content with
distinct titles; /docs/[slug] renders each markdown doc.
