What this adds

Research Runner (template) — a Bot that rents confidential GPU compute through Prism Network, runs private prompts inside a hardware enclave, and reports answer, onchain cost, and attestation verdict.

Checklist

• This PR adds exactly ONE new file under content/.
• It follows CONTRIBUTING.md — required fields + the golden rules (G1–G8).
• npm run validate passes locally (schema, slug, vocabularies).
• slug is kebab-case and exactly matches the filename.
• I ran / used this myself end to end — it works today (the Bot config from our live demo).
• Every URL in the frontmatter resolves to real, relevant content.
• The entry body is plain markdown — no raw HTML.
• I did NOT set verified_at or status: live — status is proposed.
• This is not an ad: the listing documents a working Bot configuration; the companion connector is read-only and free.
• This is our own work (sharer = Prism Network).
• I license this contribution under CC BY 4.0.
