Report #75036

[architecture] Parallel agents hanging indefinitely because one agent is waiting for an output that another agent failed to produce

Implement strict timeouts and fallback default values for any blocking inter-agent dependencies in parallel execution graphs.

Journey Context:
In a DAG where Agent C waits for Agent A and Agent B, if Agent A encounters an LLM API error or infinite loop, Agent C hangs forever. Distributed systems solve this with timeouts; multi-agent systems must do the same. Every inter-agent dependency must have a maximum wait time and a predefined fallback state so the overall workflow can still complete or gracefully fail.
