/**
 * @brief Runs the xtc-check command-line entry point.
 *
 * Supports --version, --help, and --validate PROJECT. With no arguments it
 * creates and destroys the application shell to check core startup/shutdown.
 * Any other argument count prints usage to stderr.
 *
 * @param argc Number of command-line arguments, including the program name.
 * @param argv Command-line argument vector; argv[0] is the program name.
 * @return EXIT_SUCCESS on success, or EXIT_FAILURE for invalid usage,
 *         validation failure, or core initialization failure.
