Publish production Peer groups

[0xSachinK]

Summary

• publish the production Peer, Plus, and Pro historical-taker group manifests
• use the production registry with the same reviewed metadata shape as releases/staging
• port the staging-proven bytes32 group ID schema and bump the aggregate schema to v2
• intentionally omit the removed Current Earn groups

Verification

• npm run check — validation passed for 3 groups and the aggregate built successfully
• queried indexer-preprod.zkp2p.xyz; all three IDs matched the production registry and curator, with zero resolver, private membership, and counts 1,715 / 855 / 210
