调研方向

Start with the referenced lesson code at 08/04_sugar/01/main.cu#L7 and the allocator instantiation reported at src/allocator.cu line 30. Reproduce the build with Visual Studio 2022 and CUDA 12.2, then compare the CudaAllocator usage with the compiler diagnostics in vector. Done means the lesson code builds successfully without the reported allocator conversion errors.
