Detailed Description

Backend-neutral GPU type aliases.

Every stage/pipeline/pool header spells the GPU stream/event/pool handle types as fz::stream_t/fz::event_t/fz::mempool_t instead of naming cudaStream_t etc. directly. Exactly one backend is compiled into any given build (selected at configure time via the FZGMOD_BACKEND CMake option, which defines one of FZGMOD_BACKEND_CUDA/_HIP/_SYCL) — this is a compile-time alias, not a runtime abstraction, so it costs nothing.

CUDA and HIP are implemented; the SYCL branch is added when that backend lands.
