task: add conditional compilation for GUID generation

Introduce conditional compilation in Base.cs to handle GUID generation based on the target framework version. For .NET 9.0 or greater, use `System.Guid.CreateVersion7()`. For earlier versions, continue using `System.Guid.NewGuid()`. This ensures compatibility with new features in .NET 9.0 while maintaining support for older versions.
