Report #4677

[architecture] Multi-agent collaboration loops forever or deadlocks because no agent owns the stop condition.

Set hard recursion/step limits, maximum turn counts, and explicit termination predicates. Give a supervisor or the graph runtime the sole authority to end the task, and never let individual agents decide alone whether to continue.

Journey Context:
Autonomous agents are happy to keep talking. LangGraph raises GraphRecursionError only after a configured limit; rely on that as a safety net, not a strategy. Use RemainingSteps or a step counter to degrade gracefully before the limit, and define a single node/manager that evaluates termination criteria. Without this, 'just one more round' becomes an infinite loop.
