Short zone name for an instant — "EST", "PDT", "GMT+5:30". Resolved per-instant so the
label tracks daylight saving rather than asserting one abbreviation year-round.
Comes from Intl because date-fns cannot produce an abbreviation: it ships no locale zone-name
data, so its z/zzz tokens render "GMT-5" and zzzz renders "GMT-05:00".
Returns "" for a zone Intl declines to name, so callers can omit the label rather than
print an empty suffix.
