fix(landing): proper ARIS workflow — codex review gate + audit JSON for index.html

Caught: previously rendered docs/index.html bypassed Step 5.5 of /render-html
(cross-model codex review gate), inconsistent with all 16 tutorials each
having their own .review.json audit trail.

Backfilled:
- codex GPT-5.5 xhigh fresh-thread render review (13 checks): 12 PASS + 1
  WARN on double H1 (hero h1 + content h1)
- Fixed source about.md by removing the redundant content-level H1 (hero
  H1 from template now is the sole H1)
- Re-rendered
- Saved docs/index.review.json with full audit trail (thread
  019e4048-701e-71f3-9d25-b23eeeef289c)

Now every HTML in the repo has its accompanying .review.json.
