Auto-configuration module bundling shared example tools and ephemeral session master key generation for mocapi example applications

Mocapi example app with in-memory backends — zero external infrastructure

Mocapi example app with NATS as the single distributed backplane. All four substrate SPIs (Atom, Mailbox, Journal, Notifier) run on one NATS server with JetStream enabled — the simplest possible distributed mocapi deployment.

Mocapi example app with PostgreSQL-backed McpSessionStore. Note: Substrate Mailbox/Journal/Notifier fall back to in-memory — use the Redis or Hazelcast example for full distributed deployments.
