Merge pull request 'test(m9): dump a11y hierarchy to log on UI probe failure (#128)' (#129) from feat/128-axtree-dump into milestone/m9-monterey

The probe fails on the runner with an apparently empty accessibility
tree; the xcresult artifact is not retrievable via the API. Print
app.debugDescription + window count so the tree lands in the job log.
