命令介绍
Sorted Sets 族命令用于操作按分数（score）排序的唯一成员集合，是排行榜、优先级队列、延迟任务调度等场景的核心数据结构。其核心命令按功能可分为以下五类：
成员增删与分数操作
ZADD：添加成员及其分数（支持 NX/XX/GT/LT 条件）。
ZREM / ZREMRANGEBYRANK / ZREMRANGEBYSCORE / ZREMRANGEBYLEX：按成员名、排名范围、分数范围或字典序范围删除。
ZINCRBY：原子递增成员分数，适用于实时排行榜计分。
排名与分数查询
ZSCORE / ZMSCORE：查询单个或多个成员的分数。
ZRANK / ZREVRANK：查询成员的正序/倒序排名。
ZCARD / ZCOUNT / ZLEXCOUNT：统计成员总数、分数范围内成员数或字典序范围内成员数。
ZRANDMEMBER：随机返回成员。
范围检索
ZRANGE / ZREVRANGE / ZRANGEBYSCORE / ZREVRANGEBYSCORE / ZRANGEBYLEX / ZREVRANGEBYLEX：按排名、分数或字典序范围检索成员，支持分页（LIMIT）。
ZRANGESTORE：将范围检索结果存入新键。
ZSCAN：以游标方式增量迭代。
集合间运算
ZUNIONSTORE / ZINTERSTORE：求并集或交集并存入新键（支持权重 WEIGHTS 与聚合 AGGREGATE）。
ZDIFF / ZDIFFSTORE / ZINTER / ZUNION：直接返回差集、交集、并集结果。
ZINTERCARD：快速统计交集基数。
弹出操作（队列场景，Redis 5.0+ / Valkey 8.0+）
ZPOPMIN / ZPOPMAX：弹出分数最低/最高的成员。
BZPOPMIN / BZPOPMAX：阻塞式弹出。
ZMPOP / BZMPOP（Redis 7.0+）：从多个键中批量弹出，适用于延迟队列消费与优先级调度。
