unaryop: extend sign, hyperbolic, expm1 and log1p support ( #6675 )
...
Add backend support for new UnaryOp operations across scalar, SIMD and Vulkan paths, including sign, sinh, cosh, asinh, acosh, atanh, expm1 and log1p.
Wire the new ops through onnx2ncnn and pnnx expression conversion, update generated Python emission, and add regression coverage for the new conversion paths.
Fix portability issues for expm1/log1p math declarations, NCNN_SIMPLEMATH builds, ONNX-enabled pnnx linking, and stabilize unary op tests across fp16, bf16 and torch exporter/version differences.

pnnx: fix Conv2d padding tuple normalization ( #6694 )
...
Normalize 4-element aten pad values from (left, right, top, bottom) to nn.Conv2d padding order (height, width) when fusing Conv2d modules.
Also add regression coverage for asymmetric ZeroPad2d + depthwise Conv2d to keep the output shape and ncnn pad params correct.
