[codex] Add scientific bounty sponsor scorecard

[BobbyZ2026]

/claim #18

Summary

• add a self-contained scientific bounty sponsor reliability scorecard for solver pre-commitment decisions
• evaluate funding proof, review responsiveness, rubric measurability, timeline readiness, amendment stability, payout history, dispute responsiveness, and IP/NDA clarity
• emit trusted/watch/hold tiers, sponsor improvement actions, solver guidance, public-safe audit digests, sample data, tests, requirement mapping, SVG/GIF demo artifacts, and a short MP4 demo video

Distinctness

This slice sits before solver onboarding and answers whether a sponsor/challenge is reliable enough for researchers to invest time. It does not duplicate existing intake, scoring/arbitration, appeals, workspace privacy, anti-collusion, escrow settlement, reproducibility-audit, or amendment-control modules.
