fix(init): support COMPOSER_DEFAULT_* env vars and fix abort handling

- Add COMPOSER_DEFAULT_VENDOR env var support for package name default
- Swap USERNAME/USER check order to match Composer (matters on Windows)
- Add COMPOSER_DEFAULT_AUTHOR/COMPOSER_DEFAULT_EMAIL env var support
- Require both name and email for author (Composer behavior)
- Use bail_silent for abort to prevent double error message
