fix(CRITICAL): merge 26e6cb40 build pipeline + HEAD features — fix docker build
Key changes:
1. Dockerfile: restore ex_engine COPY + build steps from 26e6cb40 (working),
add vendor_overrides staging, add ix_unified_bridge build step
2. computility-run.yaml: restore Sub168 proven params (max-model-len=80000,
gpu-util=0.95, max-num-seqs=2, enforce-eager, dtype=half) + corex env vars
3. patch_ops.sh: make vendor_overrides missing non-fatal (skip instead of exit 2)
4. New: corex_so_loader.py — unified loader for 12 prebuilt .so
5. New: moe_fused_dispatch.py — 3-tier MoE dispatch (CCCL policy_selector)
Docker build was failing because:
- HEAD removed ex_engine COPY and all build steps
- patch_ops.sh exit 2 on missing vendor_overrides killed build
- computility-run.yaml had max-model-len=262144 causing OOM
26e6cb40 scored on competition platform. This commit restores that build
pipeline while adding the new HEAD features (prebuilt .so, vllm_overrides,
corex dispatch env vars).
