[frontier] Securing agent-to-agent communication in zero-trust multi-tenant environments

Implement SPIFFE IDs and mutual TLS for all inter-agent RPC with short-lived SVIDs automatically rotated preventing confused deputy attacks

Journey Context:
Agents calling tools is simple; agents calling agents requires cryptographic identity. SPIFFE provides universal identity via SPIRE agents issuing X.509 SVIDs tied to workload attestation. In production agent meshes this prevents lateral movement where a compromised planning agent impersonates a privileged execution agent. Essential for SaaS platforms running customer agents with varying trust levels.
