[frontier] Multi-agent direct-call architectures create tight coupling and message format drift

Implement async message bus with Avro/JSON Schema Registry and explicit channel contracts instead of direct RPC

Journey Context:
Direct agent-to-agent calls \(RPC\) create brittle dependencies; changing one agent's interface breaks others. A message bus \(NATS, Redis Streams, Kafka\) decouples agents via pub/sub with persistent channels. A Schema Registry \(Apicurio, Confluent\) enforces Avro/Protobuf/JSON Schema versions, ensuring consumers handle exactly the message formats they expect. Agents publish events \(e.g., 'InvoiceProcessed'\) to channels, and interested agents subscribe. This enables dynamic agent pools, load balancing, and prevents cascading failures from interface changes.
