chore(release): v1.37.32 — Korean joins as a seventh interface language

Integrates @aucun6352's Korean locale (PR #839): the full catalog, the
NFC recompose in the shared fold, the Hangul lab-name normaliser, the
tilde range separator, and the officially published Korean PHQ-9, GAD-7
and WHO-5 wording. Resolves the CHANGELOG and OpenAPI conflicts against
the current trunk and regenerates the spec. Raises the aggregate bundle
budget to 3700 KB gz for the seventh message catalog, with the reasoning
recorded next to the value.
