debug(ci): add comprehensive build diagnostics for Windows troubleshooting

Added logging to test-setup-script to diagnose Windows build issues:
- Show working directory
- List files before build
- Run build
- List files in dist/ after build
- Verify cli.js exists

This will help identify whether:
1. Build is creating files in the wrong location
2. Files are being created but deleted
3. Build is failing silently
4. There's a working directory or path issue

Uses cross-platform commands (ls -la || dir) to work on all OSes.
