[https://nvbugs/6647310][chore] Unwaive TestLagunaXS::test_nvfp4

[sunnyqgg]

Summary

• Unwaive accuracy/test_llm_api_pytorch.py::TestLagunaXS::test_nvfp4 (waived under https://nvbugs/6647310).
• The hang was an infra issue: after the preceding test's MPI worker died, SessionPrefetcher.take() handed over a prefetched pool with no live worker, and the next test polled worker_init_status_queue until the 3600 s pytest timeout.
• The root-cause fix was merged in [TRTLLM-15302][fix] Reject dead prefetched MPI pools #17642 (commit 9d396de): take() now verifies every recorded worker's (pid, start_time) identity before handover, discards dead pools, and falls back to synchronous session creation.

Changes

• tests/integration/test_lists/waives.txt: remove the TestLagunaXS::test_nvfp4 SKIP entry.

Test plan

• Pre-merge CI (l0_b200.yml schedules TestLagunaXS::test_nvfp4).

Dev Engineer Review

• Removed the TestLagunaXS::test_nvfp4 waiver and its nvbugs/6647310 reference from tests/integration/test_lists/waives.txt.
• The change matches the one-line test-list format and does not affect other tests.
• The entry is no longer waived after the infrastructure fix in #17642.
• No code, API, performance, or error-handling changes are included.

QA Engineer Review

• No test-db or qa files were modified.
• Removed the accuracy/test_llm_api_pytorch.py::TestLagunaXS::test_nvfp4 entry from waives.txt.
• The l0_b200.yml schedule is expected to provide CI coverage.
• Verdict: needs follow-up because CBTS coverage data is unavailable.

The description explains the issue, identifies the root-cause fix, states the exact file change, and provides relevant pre-merge CI coverage.
