[Bug-Report|缺陷反馈]: run_profiling.sh masks msprof failures

run_profiling.sh runs msprof op ... 2>&1 | tail -8 with set -e but without pipefail. Reproduce this with a runner file present and an msprof stub that exits non-zero without creating a report. The wrapper currently exits 0 and prints 采集完成 when tail succeeds; it should return a failure and stop before that message.

The attention operator lab notebook expects OPPROF_* output and reads its profiling CSV files, so the masked failure surfaces later as missing profiling data. Enabling pipefail propagates the msprof error while preserving the successful capture path. A CPU stub regression confirmed a failing msprof status is propagated and the successful path still produces the expected report.
