Python probe may have been silently swallowed by build system.
Shell commands (ls, find, wc, grep) always print to stdout.

Probes:
- ls /usr/local/corex/lib64/libcorex_*.so → do .so files exist?
- ls $VLLM/model_executor/models/corex_*.py → do wrappers exist?
- find $VLLM -name '*corex*' → any corex files anywhere?
- wc/grep native qwen3_5.py → does it reference corex?

Next build log will definitively answer: can we write wrappers
for existing .so files, or must we optimize pure PyTorch?
