Root cause: EXIT trap called _k8s_test_cleanup after subshell exit,
but variables ${port} and ${test_name} were not available in that
context. set -u caught the unset variable and exited with error,
marking a successful test as failed. This caused every kubernetes
test to "fail" on attempt 1, then retry 2 more times with real
failures (NFS PVC timeout because the cluster was being deleted).
Fix: remove trap and cleanup function entirely. Pre-cleanup at
test start handles stale resources. Inline cleanup at test end
handles normal path. On failure, resources are cleaned up by
pre-cleanup on the next retry.
