cli: exit successfully for --help and --version

ApplyLaunchParams already prints the help or version text, but
SDL_AppInit then fell through to the "No ROM specified" check and
returned SDL_APP_FAILURE, so `eglantine-cli --help` and `--version`
logged a critical error and exited with a failure code. Return
SDL_APP_SUCCESS for those two options before the ROM check.

Tested: Windows and Linux CI builds; on Windows, --help and --version
exit with 0 and running without a ROM still exits with a failure.

AI disclosure: implemented with Claude and reviewed with Codex (AI
coding assistants).
