Struct ArmEthosBackend 

pub struct ArmEthosBackend;

Arm Ethos NPU backend.

Compilation pipeline:

1. Classify and validate patterns against Ethos-U support matrix.
2. Lower IR → TFLite FlatBuffer via TfLiteBackend.
3. If vela is available, invoke it on the TFLite file to produce an Ethos-U optimized binary.
4. Otherwise, emit the unoptimized TFLite with a diagnostic.
