feat(KB-136): add shared badge pub/sub for multi-instance deployments
- Add BadgePubSub interface with Redis and in-memory adapters - Implement cross-instance badge snapshot delivery via Redis pub/sub - Add message validation, echo loop prevention, and structured caching - Support graceful fallback to in-memory mode when Redis unavailable - Update ServerOptions for dependency injection and add documentation
