 * import { redisCacheAdapter } from '@abshahin/subscriptions/adapters/redis';
 * import Redis from 'ioredis';
 *
 * // With an existing client
 * const cache = redisCacheAdapter(new Redis());
 *
 * // Or with connection options (lazy-loads ioredis)
 * const cache = redisCacheAdapter({ url: process.env.REDIS_URL });
 *
 * const subs = createSubscriptions({
 *   database: prismaAdapter(db),
 *   cache,
 *   features: { ... },
