fix(interactive): Add cross-platform stdin reading support for Windows

- Implement Windows-specific stdin reading using Windows API
- Add conditional compilation for Windows and Unix-like systems
- Handle file reading differently for Windows and POSIX systems
- Ensure consistent input reading behavior across platforms
- Add error handling for Windows file reading operations
