- `Main::setup` early exits (failure or `--help`/`--version`) now consistently return `EXIT_FAILURE` or `EXIT_SUCCESS` on all platforms, instead of 255 on some and a Godot Error code on others. - `Main::start` now returns the exit code, simplifying the handling of early failures. - `Main::iteration` needs to explicit set the exit code in OS if it errors out. - Web and iOS now properly return `OS::get_exit_code()` instead of 0.
