Worked on the valkey-io/valkey repository to enhance user-facing help text and documentation, focusing on improving the clarity and accuracy of command-line guidance. Using C programming and documentation skills, updated the DELAY-RDB-CLIENT-FREE-SECOND command help text to reflect its correct plural form, ensuring consistency between the CLI and implementation. Added missing documentation for the SET-DISABLE-DENY-SCRIPTS command, aligning user guidance with the test suite and reducing potential user errors. These changes, delivered in a single commit, improved onboarding for new users and strengthened test reliability by ensuring that help entries referenced in tests were present and accurately described.
