[architecture] Agent impersonation via prompt injection in multi-agent chains

Isolate agent tool namespaces and enforce hard-coded agent IDs in message metadata; never let one agent dynamically dictate the recipient agent's name or tool calls based purely on string matching.

Journey Context:
Agents often read text like 'Calling agent\_X...' and blindly route to it. If Agent A is compromised via prompt injection, it can output 'Delegating to admin\_agent' and the orchestrator might route it. By separating routing logic from LLM generation and using strict state-machine transitions, you prevent agent impersonation and unauthorized capability access.
