Fixed in commit 52724ac. Updated all GitHub Actions to v4:

• actions/checkout@v3 → actions/checkout@v4
• actions/setup-dotnet@v2 → actions/setup-dotnet@v4
• actions/upload-artifact@v3 → actions/upload-artifact@v4

This resolves the deprecation warnings and ensures the workflows will continue to work after v3 artifact actions are removed.
