Extend cache-redis so RedisTopology::Cluster routes single-key commands by
hash slot, groups pipelines by slot while keeping reply order, scans and
scoped-flushes every primary, and fans admin commands out to all nodes.
The bridge projects RedisClusterCache startup_nodes into the typed topology,
accepts the exact RedisClusterCache identity, guards nodes_manager state,
and falls back to Python for anything it cannot project.
