[architecture] Low-confidence agent outputs cascade into expensive downstream errors

Implement confidence scoring with circuit breaker pattern: agents return confidence \[0-1\]; if below threshold, halt chain and escalate to human or stronger model

Journey Context:
Agents often produce plausible but uncertain outputs \('hallucinations with high confidence'\). Passing these to expensive tools \(code execution, API calls, or multi-step reasoning\) wastes resources and compounds errors. Simple threshold filtering fails because confidence calibration varies by model and task. The robust pattern is the circuit breaker: when confidence < θ, stop the chain and trigger fallback \(human review, stronger model, or cached safe response\). Unlike simple filtering, circuit breakers include hysteresis \(cooldown periods\) to prevent flapping. This mirrors microservice resilience patterns applied to agent cognition.
