[frontier] How to prevent cascading failures in multi-step agent workflows

Implement circuit breakers around LLM calls and tool executions to fail fast when downstream services degrade, preventing token waste and infinite loops.

Journey Context:
Agent workflows chain multiple LLM calls and tool executions. When a downstream API \(search, calculation\) slows down or fails, agents often retry aggressively, burning tokens and queue slots. Circuit breakers monitor failure rates and open the circuit after a threshold, returning cached fallbacks or degraded modes immediately. This is critical for cost control in production agents where one hanging tool can stall an entire agent swarm.
