Legion.RateLimiter.ExceededError exception (Legion v0.5.0)

Raised by a Legion.RateLimiter when a rule denies a call.

Carries the :agent_id, the :identity and :policy of the rule that denied it, the :usage the adapter measured for it, and the :violations - the policy fields that were exceeded, e.g. [:max_agents]. Legion rescues it to cancel the turn with {:rate_limited, violations}.
