Pull Request Overview

This PR enhances the Redis configuration flexibility by allowing users to provide Redis configuration in three ways: as a Redis client instance, as RedisOptions object, or as a connection string URL. This addresses issue #59 by making the plugin more convenient to use when integrating with existing Redis clients.

Key Changes:

• Modified the redis option type to accept Redis | RedisOptions | string instead of a specific object structure
• Added type guard function to detect existing Redis client instances
• Added comprehensive test coverage for all three configuration methods
