/**
 * Represents a command to execute generator files in the project's generators folder.

 * The command performs the following actions:
 * - Resolves the path to the generators folder based on the configuration.
 * - Identifies generator files that have not been executed yet.
 * - Executes only the new generator files to create tables.
 *
 * This ensures that previously executed generator files are not re-executed, maintaining efficiency
 * and avoiding duplication of database operations.
