事务没有回滚，TM报redis异常

- [x] I have searched the [issues](https://github.com/codingapi/tx-lcn/issues) of this repository and believe that this is not a duplicate.

### 1. Bug Description
只要出发分布式事务，TM就报redis异常：

我的TM配置：
```
spring:
profiles:
active: dev
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/tx-manager?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&useSSL=false&zeroDateTimeBehavior=convertToNull
username: admin
password: 123456
jpa:
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.ddl-auto: update
redis:
password:
timeout: 10000ms
cluster:
max-redirects: 3 # 获取失败 最大重定向次数
nodes:
- 127.0.0.1:6380
- 127.0.0.1:6381
- 127.0.0.1:6382
lettuce:
pool:
max-active: 1000 #连接池最大连接数（使用负值表示没有限制）
max-idle: 20 # 连接池中的最大空闲连接
min-idle: 5 # 连接池中的最小空闲连接
max-wait: -1 # 连接池最大阻塞等待时间（使用负值表示没有限制）
tx-lcn:

```

### 4. Tour Idea

Bắt đầu tại com.codingapi.txlcn.tm.core.storage.redis.RedisStorage.refreshMachines ở dòng 269, sau đó lần theo lời gọi qua ManagerServiceImpl.refreshMachines và EnsureIdGenEngine.onTmReceivedHeart. Tái hiện lỗi với cấu hình Redis cluster được cung cấp và kiểm tra stack trace discard của Lettuce. Hoàn tất khi ClassCastException không còn xảy ra trong quá trình xử lý heartbeat và rollback của giao dịch phân tán hoàn tất thành công.
