New Features

• #13915 Vector set - a new data structure [beta]:
  Vector set extends the concept of sorted sets to allow the storage and querying of
  high-dimensional vector embeddings, enhancing Redis for AI use cases that involve
  semantic search and recommendation systems. Vector sets complement the existing
  vector search capability in the Redis Query Engine. The vector set data type is
  available in beta. We may change, or even break, the features and the API in
  future versions. We are open to your feedback as you try out this new data type.

• #13863 RANDOMKEY - infinite loop during client pause
