Summary

Updated Valkey command documentation: Added CLUSTERSCAN command, enhanced CLUSTER KEYSLOT/CLUSTER SHARDS/HSETEX descriptions, and added MSETEX command

Documents new security-relevant commands (CLUSTERSCAN for auditing, MSETEX for atomic expirations) and enhanced flags (NX/XX in HSETEX) which support secure data patterns, but doesn't fix vulnerabilities.
