## What this PR does
Remove the final sandbox teardown from the two PR E2E workflows. The
runners are documented as disposable VMs, so destroying their local
containers and zpools after testing delays the result without protecting
a later run. Cleanup between preparation attempts and the Makefile
targets for reused hosts stay unchanged.
The job limit stays at 215 minutes. Suite-length budgeting, including
nightly and tag runs, remains separate in #5261. This change relies on
the existing disposable-runner contract; it does not change runner
provisioning.
