[architecture] Deadlocks where agents wait indefinitely for each other's output in cyclic dependencies

Enforce a Directed Acyclic Graph \(DAG\) for multi-agent dependencies, and implement hard timeouts on any blocking agent calls.

Journey Context:
If Agent A requires a variable from Agent B, and Agent B requires a variable from Agent A, the system halts silently or loops. While cyclic graphs allow dynamic re-planning, they introduce deadlock risks that LLMs cannot reason their way out of. Forcing dependencies into a DAG guarantees forward progress. If dynamic re-evaluation is needed, the orchestrator should initiate a new DAG pass rather than creating cycles within a single execution.
