/**
 * main - Entry point for a custom shell program.
 *
 * Description: This function implements a simple shell
 * that reads user input,
 * parses commands, and executes them.
 * It provides a command-line interface with
 * basic functionality, including command execution
 * and the "exit" command to
 * exit the shell.
 * @argc: input
 * @argv: input
 * Return: Always returns 0.
