📝Changelog

Upgrade

• Cert: Rework certifier governance flow — new typed MsgUpdateCertifier with Add/Remove enum replaces the legacy proposal path. Submissions are now restricted to registered certifiers.
• Cert: Introduce 5 secondary certificate indexes (by certifier, type, certifier+type, content hash, type+content hash). Filtered queries and IsCertified / IsContentCertified now use prefix iteration instead of full-store scans, significantly reducing gas on large certificate sets.
• Cert: Migrate keeper storage to cosmossdk.io/collections.
• Cert: Add OpenMath certificate type and expand test coverage.
• Gov: Simplify certifier-update voting path.
• Bounty: Enforce OpenMath proof submission restrictions; enrich event metadata for better indexer visibility.
