[architecture] Low-confidence LLM outputs propagate causing compound errors in agent chains

Implement per-agent confidence scoring using logprob aggregation or self-consistency voting; if confidence < threshold, circuit-break to human-in-the-loop or deterministic fallback agent

Journey Context:
Many agent chains naively pass LLM outputs forward. When Agent A hallucinates, Agent B treats it as ground truth and compounds the error. Confidence thresholds act as a firewall. The circuit breaker pattern prevents cascading failures by stopping the chain early. Alternative is ensemble voting, but that's expensive; confidence scoring using logprobs is cheaper.
