feat: add redis driver identification

[vchomakov]

Summary

Adds getClientInfoTag helper function for Redis driver identification.

Changes

• Added getClientInfoTag() helper that returns a client info tag like neshca-cache-handler_v1.9.0
• Added tests for the helper
• Updated documentation examples to use the new helper

Why

This helps identify the library using the Redis client in CLIENT LIST output, useful for debugging and monitoring Redis connections.

Usage

import { getClientInfoTag } from '@neshca/cache-handler/helpers';

const client = createClient({
  url: 'redis://localhost:6379',
  clientInfoTag: getClientInfoTag(),
});
