- Updated convolution reference to branch epilogue: * TO=float: int32 to float dequant (acc * sA * sB + bias_f32) * TO!=float: usual quantize_down_scale_by_fixedpoint with int32 bias - Changed fixture to use F32 bias tensor for Q->F32 runs (instead of S32), matching arm_gemm dequant epilogue which only supports float bias. - Added explicit template instantiations for convolution_layer with TBias=float, TO=float to fix linker errors in validation. - Disabled activation in arm_gemm dequant path: offsets are applied afterwards by CpuGemmLowpOffsetContributionKernel, so activation must run there to see the correct final accumulator. This aligns target and reference for quantized to F32 convolution tests and prevents premature clamping before offset contributions.
