Contributor guide

Research direction
Study the existing Redis command implementations in the codebase, particularly the string command handler pattern. Implement the missing string commands (SET with NX/XX/EX/PX, GETSET, STRLEN, etc.) by following the same structure, including argument parsing, encoding, and interaction with RocksDB.
