"""Simple Notepad test task for native Windows environments.

This task tests real Windows application interaction WITHOUT webview/bench_ui:
- Launches Notepad using Windows shell
- Types text
- Saves file
- Evaluates by checking file contents on disk

No webview, no HTML - just real Windows app automation.
