/**
 * Creates a plugin that prefixes all keys passed to a circuit-breaker adapter.

 * prepended before the call is forwarded to the underlying adapter. This is
 * useful for namespacing circuit-breaker state when multiple independent
 * consumers share the same backend.
 *
 * @param prefix - The string to prepend to every circuit-breaker key.
 * @returns A middleware plugin that wraps an `ICircuitBreakerAdapter`.
