[https://nvbugs/6507114][fix] Extend the per-model qwen3.5_moe_35b.yaml with…

[trtllm-agent]

Summary

• Root cause: Two independent AutoDeploy compile-pipeline defects stack on this test: multi_stream_moe/gemm stall the SM90 TP=4 GSM8K "Fetching responses" loop, and default piecewise CUDA-graph capture silently kills a worker on the first multi-image MMMU prefill for the Qwen3_5MoeForConditionalGeneration VLM.
• Fix: Extend the per-model qwen3.5_moe_35b.yaml with compile_model.piecewise_enabled: false alongside the multi_stream_moe/gemm disables (scoped to this model config only, matching super_v3.yaml/super_v3_mtp.yaml precedents); remove the stale waives.txt entry.
• Automated fix generated by repair-bot

Test plan

• Verify fix on the same GPU type as the original failure
• Check for regressions in related tests

Dev Engineer Review

• Disabled piecewise CUDA-graph capture and multi-stream MoE/GEMM transforms for Qwen3.5-35B, addressing known GSM8K stalls and MMMU prefill worker termination.
• Changes are scoped to the model configuration, retain stage: compile, and align with model-specific precedents.
• Removed the stale Qwen waiver entry from waives.txt; formatting and ordering remain consistent.
• No public API or code changes; no apparent regressions.

QA Engineer Review

• Test-list-only change: removed accuracy/test_llm_api_autodeploy.py::TestQwen3_5_397B_MoE::test_bf16_small[4] from tests/integration/test_lists/waives.txt.
• No test-db/ or qa/ files were modified.
• End-to-end validation passed on 4×H100: MMLU 84.75, GSM8K 88.97, and MMMU 59.89.
• Verdict: needs follow-up because CBTS coverage data is unavailable.

Walkthrough

The Qwen 3.5 MoE auto-deploy configuration disables selected compile features and adds a compile-model setting. Its waived BF16 integration test is removed from the integration waiver list.
