# Collects and prints macOS crash reports after a failed plugins e2e run.
#
# The CrabNebula Webdriver proxies every command to a server running *inside* the app
# process, so when the app dies the suite only ever reports `connection refused` — the
# actual cause is never in the job log. The app's stdout/stderr is inherited and no panic
# message is printed, which means it goes down on a signal. macOS records the reason in a
# crash report, and that is the only place it survives the run.
#
# Copies every report into $1 (default: $RUNNER_TEMP/crash-reports) for upload.
