Resolves #735

Description

Adds clientInfoTag support to the Redis driver to leverage Redis's CLIENT SETINFO command.

This feature helps Redis administrators identify which higher-level library is using ioredis by setting a custom tag in the CLIENT SETINFO LIB-NAME command.

Changes

• Added clientInfoTag option to RedisOptions interface
• Automatically sets tag to unstorage_vX.X.X using package.json version
• Supports custom clientInfoTag override
• Handles cluster mode by passing tag through clusterOptions.redisOptions
• Added tests for default and custom clientInfoTag behavior
• Updated documentation

Example Usage

// Default behavior - automatically includes version
const storage = createStorage({
  driver: redisDriver({
    host: 'localhost',
    port: 6379
  })
});
// Results in: CLIENT SETINFO LIB-NAME ioredis(unstorage_v2.0.0-alpha.5)

// Custom tag
const storage = createStorage({
  driver: redisDriver({
    host: 'localhost',
    port: 6379,
    clientInfoTag: 'my-app_v1.0.0'
  })
});
// Results in: CLIENT SETINFO LIB-NAME ioredis(my-app_v1.0.0)
