chore(release): v1.33.2 — the cycle-symptom fix that did not reach the file

v1.33.1 claimed custom cycle symptoms were carried in backups. They were not,
and the same release turned the old silent drop into a hard failure, so the
accounts the fix was written for went from losing one symptom link to being
unable to restore at all.
