/**
 * MinMaxQueue implementation in Redis using a single sorted set
 *
 * ## Data Structure
 * - Uses a Redis sorted set where:
 *   - Score: timestamp when value was added (seconds since epoch)
 *   - Member: the actual bigint value (stored as string)
 *
 * ## Flow
 * 1. **Adding values**: New values are added/updated with current timestamp as score
 * 2. **Reading values**: Queries filter out expired entries based on timestamp
 * 3. **Cleanup**: Background process runs every minute to remove expired entries
 *
 * ## Optimization Strategy
 * - Lazy cleanup: expired entries filtered on read, bulk removed by background process (removing is expensive)
 *
 * ## TTL Management
 * - Entries expire based on `queueValidity` (configured via `gasPriceExpiry`)
 * - Background cleanup prevents unbounded growth
 * - Read operations ignore expired entries without removing them
