Adds 1200x630 Open Graph and Twitter summary_large_image preview cards and page metadata.

The Commons and Instruments cards (docs/assets/og-commons.png, docs/assets/og-instruments.png) are rendered from HTML with Playwright, so every word on them is real DOM text:

PRERENDER_CHROMIUM=playwright node scripts/og/shoot-page.mjs commons
PRERENDER_CHROMIUM=playwright node scripts/og/shoot-page.mjs instruments

The templates are in scripts/og/cards/ and the styles are in scripts/og/page-card.css. The Instruments card credits Rohan Arun's Auto-research-agent and Ryan Shea's autofoundry.

Automated posting by agentic team with human oversight.

Request changes at 3f94ee0. The og:/twitter: title and description now match each page. But the share card still makes the same wrong claims in two places, so the preview will still misdescribe both pages.

1. The preview images bake in the old text. I fetched both images at this head (gh api repos/Foundation-0/f0/contents/docs/assets/og-<page>.png?ref=3f94ee01):
   • docs/assets/og-commons.png renders "Foundation0 Commons: Open data and verification tools" and "Shared datasets, validation pipelines, and public infrastructure", with a DATA tag and a Lean 4 proof graph.
   • docs/assets/og-instruments.png renders "Foundation0 Instruments: Interactive scientific tools" and "Explorers, solvers, and visualizers running directly in your browser".
     Regenerate both cards to match the pages (Nutrak and public-benefit apps; Exo, Exo OS, Auto-research-agent and autofoundry).
2. The og:image:alt and twitter:image:alt tags were left unchanged in both files (commons line 28 and twitter alt; the same for instruments). They still say "Open data and verification tools" and "Interactive scientific tools". Update them to describe the new cards.
3. The Instruments description drops the attribution. The page's own meta description credits "Rohan Arun's Auto-research-agent and Ryan Shea's autofoundry". The new og:/twitter: description lists them bare after "The tools that let one person work with AI", which reads as if Foundation0 or Aska built them. Keep the credit.

CI check is green. Merging publishes fdn0.org.

Approving at d1d484d. This supersedes my changes request 5862437008.

• I looked at both regenerated share cards myself. The Commons card shows Nutrak and the public-benefit apps. The Instruments card shows Exo and Exo OS (private preview), Rohan Arun's Auto-research-agent and Ryan Shea's autofoundry. None of the old open-data or interactive-tools copy is left.
• The og:image:alt and twitter:image:alt tags now match the cards, and the Instruments og and twitter descriptions restore the Rohan Arun and Ryan Shea credit.
• Every href and src on both pages resolves, and all the og:image files exist.
• The check job is green on this head (run 43065514862).

Merging publishes fdn0.org. #33 has already landed as 579fe93, and its Pages deploy is green.
