Thanks for the PR! A couple of points and questions:
1. Status of GNA vs NPU
- The upstream GNA repo is archived and marked as not under active
management. The OpenVINO docs also note that GNA is being discontinued and
recommend using Intel's NPU as the low-power offload path on newer processors.
Given that, would it make sense to position this backend as a stepping stone
toward NPU (and/or clarify the long-term maintenance plan in the README/code
comments)?

2. CI & Software Emulation Mode
- According to the OpenVINO docs, GNA plugin supports Software Emulation
Mode (CPU fallback) when GNA HW isn't present. If we enable that in tests, we
could run E2E coverage in our CI.
I also think this backend can serve as a very good example for codegen in
Relax. It shows a clean and minimal pattern: partitioning with basic ops,
handing off to JSON, and keeping the implementation relatively lightweight.
Adding a short HOWTO or developer note ("Writing a minimal Relax backend") that
references this code could be very helpful for the community.
