[frontier] Cascading failures when external APIs timeout or hallucinate in agent tool chains

Implement circuit breakers that monitor error rates and latency, failing fast when downstream tools exhibit degraded behavior

Journey Context:
Agents calling tools in chains suffer from cascading latency when downstream services degrade. Without circuit breakers, agents wait for timeouts, exhaust resources on retries, and propagate failures across the swarm. Circuit breakers monitor error rates and latency percentiles, opening the circuit after thresholds to prevent resource exhaustion. This enables graceful degradation to cached responses, simplified workflows, or explicit failure signals rather than hanging indefinitely.
