 * Creates a plugin that prefixes all keys passed to a rate-limiter adapter.

 * prepended before the call is forwarded to the underlying adapter. This is
 * useful for namespacing rate-limiter state when multiple independent consumers
 * share the same backend.

 * @param prefix - The string to prepend to every rate-limiter key.
 * @returns A middleware plugin that wraps an `IRateLimiterAdapter`.
