瘦身: Kafka/MongoDB/Cassandra用raw TCP替代重型依赖

- kafka: 移除IBM/sarama(45MB), 自实现SASL PLAIN+ApiVersions协议(~150行)
- mongodb: 移除mongo-driver(25MB), 自实现OP_MSG+saslStart认证(~180行)
- cassandra: 移除gocql(1.2MB), 自实现CQLv4 STARTUP+SASL PLAIN(~130行)
- 同时移除间接依赖: pierrec/lz4, klauspost/compress, eapache/snappy等

二进制: 47MB → 40MB (-15%), 移除~55MB压缩依赖
全部13个测试包通过
