Is your feature request related to a problem? Please describe

The DUMP command serializes a value at a specified key and dumps the serialized value to the client. The serialized value can then be deserialized and stored using the RESTORE command.

Currently, Garnet supports the DUMP & RESTORE commands for string values only. We're looking for help implementing this command for all other supported object types (Set, SortedSet, HashSet, List).

Describe the solution you'd like

Extend implementation of DUMP and RESTORE command in Garnet to support objects.

Research direction
Start by studying the existing DUMP and RESTORE implementation in KeyAdminCommands.cs (libs/server/Resp/KeyAdminCommands.cs). Understand the RDB serialization format specification linked in the issue. Then extend the code to handle serialization and deserialization for Set, SortedSet, HashSet, and List types, following the pattern used for strings. Test the commands and ensure compatibility with the Redis dump format.
