[architecture] Privilege escalation via confused deputy attacks in tool chains

Enforce Mandatory Access Control \(MAC\) labels at agent boundaries; agents cannot invoke tools with higher privilege levels than their own; sanitize tool descriptions to prevent instruction leakage

Journey Context:
Low-privilege agents exploiting high-privilege agents' tool access is the confused deputy problem. Discretionary access control fails because agents act on behalf of users. MAC with information flow control prevents privilege escalation even when agents are compromised, by binding capabilities to immutable security labels.
