test: 回退Docker context到26e6cb40完全一致——验证竞赛平台build

Dockerfile/qwen3_6_scripts/ex_engine/computility-run.yaml 全部
还原到26e6cb40的精确内容。删除所有26e6cb40不存在的新增文件
(prebuilt/*.so, wheels/*.whl, vendor_overrides/, 新增.cu/.sh等)。

目的：确认26e6cb40的文件内容在当前git状态下仍能通过竞赛平台build。
如果通过，说明问题在新增文件中；如果不通过，说明问题在git仓库层面。

-precompile_ix_bridge.py — Compile ix_moe_bridge.cpp → ix_moe_bridge.so
-
-Links against libixformer.so in the base image to expose:
-  - topk_softmax (the missing vllm_moe_topk_softmax)
-  - moe_gen_idx, moe_expand_input, moe_group_gemm
-  - silu_and_mul, moe_combine_result
-  - paged_attention, rms_norm, linear, reshape_and_cache, rotary_embedding
-
-Build chain:
-  precompile_ix_bridge.py
-    → torch.utils.cpp_extension.load("ix_moe_bridge", ...)
-      → g++ -shared ix_moe_bridge.cpp -lixformer -L/path/to/ixformer
-        → ix_moe_bridge.cpython-310-x86_64-linux-gnu.so
