Summary
HYBRID_EP_MULTINODE=1in both production Dockerfiles.HYBRID_EP_MULTINODEin the uv seed compatibility key so stale single-node wheels are skipped without deleting reusable multi-node wheels.docker/install_apptainer.shunchanged because it installs Apptainer and does not build DeepEP.Why
DeepEP reads
HYBRID_EP_MULTINODEwhile building its extension. Setting the variable only at runtime cannot add inter-node transport support to an existing single-node wheel.This change also enables multi-node AutoModel HybridEP recipes proposed in #4037.
