ruv 5cacb5fe0a perf(nn): zero-copy ORT input (~1.48x) + dynamic-dim guard + concurrency bench (ADR-155 §Tier-3)
- onnx.rs ORT input: arr.as_slice() single-memcpy fast path with iterator
  fallback for strided views. MEASURED [1,256,64,64]: 1.972ms -> 1.336ms
  (~1.48x). Repro: cargo bench -p wifi-densepose-nn --no-default-features
  --features onnx --bench onnx_bench -- onnx_input_copy
- onnx.rs checked_output_dims: reject ONNX dim <= 0 (incl. unresolved -1) before
  allocation (config-OOM class) + test.
- onnx_concurrency bench: empirically proves the per-inference write lock
  serializes (throughput drops with more threads). The intended read-lock win is
  NOT landable on ort 2.0.0-rc.11 (safe Session::run is &mut self, verified) and
  is deferred to the backlog with the upgrade path documented in-code.

New committed fixture tests/fixtures/tiny_conv.onnx (666 B, not gitignored).
