Upgrade .NET Framework projects to .NET Framework 4.8.1 (net481), staying on full .NET Framework without migrating to modern .NET (net8.0+). Use when user explicitly asks to upgrade to .NET Framework 4.8.1, upgrade to the latest .NET Framework version, or stay on full/Windows .NET Framework. Preserves legacy vs SDK-style project format unless the user explicitly requests SDK-style conversion.
