[frontier] Cascading agent failures causing infinite retry loops and system hangs when external tools are down

Implement circuit breakers in agent graphs: after 2 consecutive failures of a subgraph/tool, route to a fallback agent \(graceful degradation\) and block further calls for 60 seconds

Journey Context:
Agent graphs often implement naive retry logic \(exponential backoff\). When a downstream API is down, this creates a retry storm that blocks the entire swarm. The circuit breaker pattern \(from microservices\) is being adapted: track failures per tool/agent, and when a threshold is hit, fast-fail to a fallback \(cached result, simpler model, or human handoff\). This prevents one bad tool from killing the entire agent session.
