feat: add bytecode consistency review for module deployment PRs

Summary

• update-registry.yml writes new addresses with zero on-chain verification, only format checks. Nothing confirms the bytecode is actually correct.
• Unlike safe-deployments, this schema has no stored codeHash per chain, so adds a Review workflow (mirrors safe-deployments' review.yml) that instead cross-checks: on PRs touching src/assets/**, diffs each changed file against the base commit to find which chain(s) changed, then verifies each one's bytecode hash against an already-registered reference chain (deterministic CREATE2 deploys must be byte-identical everywhere).
• Only changed chains are checked, and all of them are checked before failing (not just the first broken one).
