CUTLASS grouped GEMM (example 24) requires SM80 Tensor Core + cuda/std headers.
Cannot compile on corex (same issue as CCCL 3.6 variadic functions).
Alternative path: ix_moe_bridge.so calls ixformer::infer::moe_w16a16_group_gemm
which is BI-V100 optimized grouped GEMM already in the base image.
This probe script checks if the MoE functions exist in ixformer .so
before attempting to build ix_moe_bridge.so.
Run: bash qwen3_6_scripts/probe_ixformer_symbols.sh
