The default CUDA architecture was sm_100 (Blackwell) only, so a default build did not run on Ada/L40 (sm_89) hardware without passing -DCMAKE_CUDA_ARCHITECTURES=89.

Default to building both 89 and 100, so a stock build runs on L40 and Blackwell. An explicit -DCMAKE_CUDA_ARCHITECTURES=... still overrides.
