/**
 * CircuitBreaker — IDS Story IDS-5a
 *
 * Implements the Circuit Breaker pattern for graceful degradation.
 * Prevents cascading failures by tracking consecutive failures and
 * opening the circuit when a threshold is reached.
 *
 * States:
 *   CLOSED  -> Normal operation, requests pass through
 *   OPEN    -> Failures exceeded threshold, requests short-circuit
 *   HALF_OPEN -> After reset timeout, allows one probe request
