* Use platform-specific APIs for environment variables

The previous patch used `putenv` as a quick fix for Windows compatibility. However, `putenv` is a legacy API and not the recommended choice.

- On Windows, it now uses the modern and secure `_putenv_s`.
- On Unix-like systems, it uses the standard `setenv`.
