Upgrades the vLLM-Omni AL2023 EC2 + SageMaker images to DeepEP v2 over EFA (same recipe as the vLLM PR).

Changes

  • vLLM core → 0.29.0 (via vllm_ref); vllm-omni → 0.29.0rc1 (no stable 0.29.0 yet — draft until it ships)
  • DeepEP → AWS EFA fork amazon-contributing/DeepEP@874779c, built as a wheel from the fork
  • NCCL → 2.31.2 (pip wheel); NVSHMEM via pip wheel nvidia-nvshmem-cu13
  • GDRCopy 2.5.2 built from source (net-new)
  • EFA 1.47.01.50.0 (auto --disable-ngc)
  • flashinfer → 0.6.18; add instanttensor + modelexpress
  • dlc_minor_version 6 → 7

Validation: DeepEP internode (test_ep.py on 2x p5en) pending capacity; draft until validated and vllm-omni 0.29.0 stable.
