More apple metal woes

So I checked out other issues, this is a different issue altogether to any I can find so far

M1 Ultra 128GB RAM

I have replaced my home directory with $HOME; so you dont need to debug that.

Start with the vllm/v1/engine/core_client.py and vllm/v1/engine/utils.py entries in the reported traceback, then reproduce the runner startup failure on the listed M1 Ultra system. The missing root cause above the traceback must be identified before the runner can be considered fixed; verify that a model request completes successfully afterward.
