[architecture] Cascading failures when one agent in a chain degrades or hallucinates

Implement a circuit breaker with a 50% error threshold over a 60-second rolling window; when open, fail fast and return a structured error with a \`retry\_after\` hint instead of propagating garbage outputs

Journey Context:
When Agent B in an A→B→C chain starts producing low-confidence or malformed outputs due to model drift or prompt injection, Agent C wastes compute attempting to parse garbage, often producing worse hallucinations. Simple timeout-based retries exacerbate the problem. The circuit breaker pattern monitors error rates \(schema validation failures, confidence below threshold, or latency spikes\) and temporarily halts traffic to the failing agent, allowing it to recover or triggering an alert for human intervention. This prevents error amplification across the chain.
