[synthesis] Tool availability drift causes cascading timeouts without circuit breaking

Implement circuit breaker pattern \(closed/open/half-open states\) with exponential backoff, explicitly surfacing tool unavailability to agent rather than infinite retry loops.

Journey Context:
Without circuit breakers, a degraded tool causes every agent loop to wait for timeouts, cascading slowness across the system. Simple retries hammer the struggling service. The circuit breaker pattern seems aggressive \(failing fast\), but it preserves system resources and forces explicit fallback logic. The half-open state allows graceful recovery detection, ensuring the agent knows when tools are healthy again rather than assuming permanent failure or success.
