🟢 Approval recommended

The change is narrowly scoped, follows the established PALTests exclusion mechanism, and includes a tracking issue for follow-up.

Pull request overview

This PR updates the PAL test exclusion list to skip a single flaky PAL test when running on macOS arm64, aligning the generated PAL test list with known platform instability for that scenario.

Changes:

  • Add an ExcludeList entry for exception_handling/pal_sxs/test1/paltest_pal_sxs_test1 gated on TargetOS=osx and TargetArchitecture=arm64.
  • Link the exclusion to the tracking issue so it’s discoverable and reversible.
