Description
Currently the GPU Vamana build uses a custom kernel here.
This needs to be replaced with a RAFT primitive to avoid excessive kernel definitions and simplify the codebase. However, it's not a standard access pattern so needs to be done with a strided view or something similar.

Research direction
The linked custom GPU Vamana scatter kernel is the entry point; inspect its access pattern and the surrounding build path first. Replace that kernel with an equivalent RAFT primitive using a strided view where needed, then verify the Vamana build behavior and relevant existing checks.
