Publish canonical repository KAG indexes

[8Dionysus]

Summary

• publish the complete seven-file repo-self KAG family under kag/indexes/
• preserve this repository's owner-specific KAG indexes and source-return routes
• pin the owner-callable validation lane to aoa-kag 956134dccb744f7f46a3aba8a9d60df9baf1aa69
• align local validators and generated owner surfaces where this repository required it

Validation

• deterministic full rebuild parity
• dependency-aware incremental parity
• repository-family schema, ownership, namespace, and reference contract
• clean post-commit parity after two successive KAG commits
• repository owner gates were exercised during rollout; GitHub validation remains the landing authority.
