[architecture] Cascade failures when downstream agents degrade or hallucinate

Implement circuit breakers that trip when error rates exceed thresholds or confidence scores drop below configurable limits, returning fast failure rather than propagating garbage.

Journey Context:
In multi-agent chains, one slow or hallucinating agent creates backpressure and timeout cascades. The naive fix is retries with exponential backoff, but this amplifies load on already-failing services. Circuit breakers monitor error rates or confidence scores and open after thresholds \(e.g., 50% error rate in 30 seconds\), immediately failing fast and giving the system time to recover. This prevents resource exhaustion and allows fallback to degraded modes or human escalation. The tradeoff is temporary reduced availability vs. total system collapse.
