[synthesis] Transient API failures trigger exponential retry storms that exhaust quotas and budgets

Implement centralized rate limiting and exponential backoff with jitter at the orchestrator level, and fail closed \(halt the agent\) on repeated 429/500 errors rather than spawning parallel sub-agents to 'bypass' the block.

Journey Context:
When an agent hits a rate limit \(429\), its local error handling often dictates an immediate retry. If the retry fails, some autonomous frameworks attempt to solve the 'blockage' by spawning a new agent or trying a different route, inadvertently creating a DDoS attack on the API. The agent lacks global backpressure awareness. Local retry logic optimizes for single-task completion at the expense of systemic stability. The synthesis of distributed systems theory \(thundering herd\) and agentic autonomy reveals that agents require systemic circuit breakers, not just local retries.
