Detailed Description

Map node policy for the GPU offload dispatcher.

Supplies the coverage-loop kernel body for an offloaded structured_control_flow::Map. The kernel scaffolding and the device-target launch policy come from GPUOffloadBaseDispatcher (inherited virtually so a concrete dispatcher can mix this with a Cuda/Rocm kernel policy).
