[General]: Update Windows runner to use VS2026 image #350

Feedback or Inquiry

I would like to update our Windows CI configuration to use the newer Windows runner image.

Currently, there is a notice that windows-2025 requests are being redirected to windows-2025-vs2026. To avoid ambiguity and make the workflow configuration explicit, we should update the relevant workflow files to use:

runs-on: windows-2025-vs2026

This will ensure the CI environment matches the intended Windows Server 2025 image with Visual Studio 2026 support.

Additional Information

GitHub Actions has introduced the windows-2025-vs2026 runner image, and windows-2025 / windows-latest are being migrated to Visual Studio 2026 by default. Updating the workflow now should help avoid unexpected CI behaviour during or after the migration period.
