[architecture] Overly permissive agent-to-agent trust enabling lateral movement after compromise

Implement capability-based security: agents hold unforgeable tokens \(capabilities\) granting specific rights; each agent receives least-privilege capabilities for its current task only

Journey Context:
If every agent can call any tool or access any data, a compromised agent can wreak havoc across the system. Use capability-based access control instead of ACLs: Agent A receives a 'capability token' \(cryptographic unforgeable reference\) allowing exactly 'read:customer:123' for 5 minutes. It cannot forge access to customer 456 or write access. This contains blast radius and prevents lateral movement even if an agent is compromised.
