Tighten PR review findings and state record publishing

[fuller-stack-dev]

Summary

• keep missing/mock-only real behavior proof from short-circuiting the PR code/docs review pass
• add targeted review prompt checks for task/media duplicate guards, request scoping, fallback delivery, and docs/code contract drift
• preserve newer durable review records during state publishes, including broad records syncs and exact record-file syncs, while retaining state-only job/PR egg preservation

Investigation

• The first ClawSweeper run on fix: directly deliver completed media fallback openclaw#84371 stopped at mock-only proof and recorded no code findings.
• A later re-review did catch the P1/P2 findings and synced the public review comment, but a later broad state publish reverted the durable record to the older no-findings report.

Testing

• pnpm run check on Node 24.14.0
