rateLimits

Rate limits for task dispatches. The queue's actual dispatch rate is the result of:

• Number of tasks in the queue

• User-specified throttling: rateLimits, retryConfig, and the queue's state.

• System throttling due to 429 (Too Many Requests) or 503 (Service Unavailable) responses from the worker, high error rates, or to smooth sudden large traffic spikes. Structure is documented below.
