Migrate all scheduled jobs off functions.pubsub.schedule().onRun() to
firebase-functions/v2/scheduler onSchedule({ schedule, timeZone, ...opts }, handler):
sendChallengeDayReminders, unlockDueMemoryCapsules, sendDailyQuestionProactiveReminder,
sendStreakReminder, sendReengagementReminder, assignDailyQuestion (scheduled export),
aggregateOutcomeStats, scheduledOutcomesReminder.
Hardening folded in:
- Fan-out isolation: Promise.all → Promise.allSettled in dailyQuestionReminder (outer+inner),
reengagement, gameRetention (both jobs), scheduledOutcomesReminder — one bad couple can no
longer abort a whole run. streakReminder / assignDailyQuestion already isolated.
- Resource options: assignDailyQuestion + aggregateOutcomeStats memory 512MiB + timeout 300s
(they iterate all couples); the four fan-out reminders get timeout 180s.
- Adopt shared sendPushToUser()/logger everywhere; remove five copied getUserTokens() and the
copied send/prune blocks (no plaintext token logging remains here).
- Consolidate duplicated date/time helpers into notifications/time.ts (chicagoDateKey, toMillis),
replacing streakReminder's + scheduledOutcomesReminder's per-file copies.
assignDailyQuestion.ts callable export stays v1 for now (migrates in B3); its tested CST helpers
are untouched. Scanner pagination for assignDailyQuestion/aggregateOutcomes is deferred to B6.
Build clean; 70 tests green (tested pure helpers preserved). dist rebuilt. Still on v5.1.1.

Tracked dist output rebuilt to match src (aggregateOutcomeStats export +
aggregateOutcomes module), keeping the deployed bundle in sync with source.
