Leaderless Peer Discovery & High Availability

nogoo9 achieves High Availability (HA) and multi-replica scalability without stateful databases (Postgres, Redis, or Etcd) by employing a Kubernetes Secret-backed peer discovery mechanism ([src/server/peer-discovery.ts](file:///home/eterna2/github/nogoo9-no-crd/src/server/peer-discovery.ts)).

🛡️ Guarantees

1. Zero Database Dependency: Eliminates external database infrastructure for session state management.
2. Atomic Conflict Resolution: Simultaneous replica boots resolve races cleanly through Kubernetes API atomic secret creation semantics (409 Conflict fallback to read).
3. Seamless Stateless Scaling: Any replica can decrypt session cookies (nocr_sess) and refresh tokens (nocr_refresh) issued by any other replica.
