Note

Adds slot-range (binary and human-readable) serialization and wires coordinator slot ranges from topology into commands/iterators and through FT parsers, with debug parsing tweaks and extensive tests.

• Slot Ranges Core:
  • Add binary serialize/deserialize helpers and size calc in slot_ranges.{c,h}.
  • Add RedisModuleSlotRangeArray_FromClusterShardsReply to build ranges from CLUSTER SHARDS.
• Coordinator/Topology:
  • Store per-shard slotRanges in MRClusterShard; clone/free updated in cluster_topology.
  • Parse slot ranges from cluster reply in redis_cluster.c.
• Command/Iterator Wiring:
  • New helpers MRCommand_AddSlotRangeInfo and _HumanReadable to append _RANGE_SLOTS_BINARY/_RANGE_SLOTS_HR.
  • Iterators attach slot-range info to each shard command in rmr.c.
• Query Parsing (Aggregate/Hybrid):
  • Support _RANGE_SLOTS_BINARY and _RANGE_SLOTS_HR args; plumb via ParseAggPlanContext/HybridParseContext into AREQ->coordSlotRanges; free on request cleanup.
  • Update structs (aggregate.h, hybrid parse) and compile paths to handle coord slot ranges.
• Debug/Exec:
  • Adjust DEBUG_PARAMS_COUNT parsing to allow presence/absence of slot-range args; propagate count in exec paths.
• Tests:
  • Add C++ tests for command slot-range appending/round-trip, slot-range (de)serialization and comparisons, and aggregate compile with slot-range args.
