[architecture] One slow or failing agent blocks the entire multi-agent pipeline, causing cascading timeouts

Implement circuit breaker and timeout patterns at every agent call; after N consecutive failures, short-circuit the agent and route to a fallback or escalation path.

Journey Context:
In multi-agent pipelines, if Agent B is slow \(API rate limit, model overload\) or failing \(repeated validation errors\), it blocks Agents C, D, and E downstream. The pipeline hangs or times out globally. The circuit breaker pattern solves this: after N consecutive failures from Agent B, open the circuit — stop calling Agent B and route to a fallback \(simpler model, cached response, or human escalation\). After a cooldown period, try again \(half-open state\). The tradeoff is that you need fallback paths for every agent, which adds complexity, but without circuit breakers, one degraded agent can take down the entire system. This is a well-proven pattern from microservices architecture that applies directly to multi-agent systems with external API dependencies.
