[CI][Intel XPU] Isolate test_outputs.py into its own pytest process in "V1 Sample + Logits" to avoid intermittent failure

[mayuyuace]

test_sampling_mask_tensors_match_finite_support[512] intermittently fails on Intel XPU CI when run in the same pytest process as preceding heavy test suites; splitting test_outputs.py into its own pytest invocation avoids the race.

CI-only config change, no production code touched. Underlying race not fully root-caused, this is a mitigation.

📝 Summary

Summary by CodeRabbit

• Tests
  • Updated Intel CI test execution so output validation runs separately from oracle and request tests.
  • Test groups now stop immediately when an earlier group fails.
  • Improved sharded test handling so jobs succeed when no tests are assigned to a shard, while still reporting other failures.
  • Preserved failure reporting for all other test execution errors.

Walkthrough

Intel CI runs V1 output tests in a separate pytest invocation. The Intel test runner handles exit code 5 for empty shards when the pre-shard selection is non-empty.

Changes

Intel CI test execution

Layer / File(s)	Summary
Split V1 test invocations .buildkite/intel_jobs/misc_intel.yaml	The job runs oracle and request tests together, then runs output tests in a separate pytest command chained with &&.
Handle pytest shard statuses .buildkite/scripts/hardware_ci/run-intel-test.sh	When PYTEST_ADDOPTS is set, the wrapper captures pytest output. It converts exit code 5 to success only when the shard runs zero items and the pre-shard selection is non-empty. Other exit codes propagate unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 5ea90

Intel CI now runs the V1 output tests separately to avoid order-dependent flakes while retaining failures for non-empty test shards. No current merge-blocking risk remains.

- Line 390: Update the exit-code handling around the ec check to parse the
collected and deselected counts from the pytest log, calculate the selected
count as collected minus deselected, and accept exit code 5 only when that count
is positive and the shard count is zero. Preserve rejection for empty selections
and existing behavior for other exit codes.
