 * Refresh Commands - Reload custom commands from filesystem
 *
 * This command provides a runtime mechanism to refresh the custom commands
 * cache without restarting the application. It's particularly useful during
 * development or when users are actively creating/modifying custom commands.
 *
 * The command follows the standard local command pattern used throughout
 * the project and provides detailed feedback about the refresh operation.
