/**
 * Proactive daily question reminder.
 *
 * Schedule: 4:00 PM America/Chicago (2 hours before the question expires at 6 PM).
 *
 * Logic:
 *  1. Query all `daily_question` docs (collection group) with expiresAt in the
 *     next 3 hours — these are the ones expiring today.
 *  2. For each, count the answers subcollection. If 0 answers (neither partner
 *     has responded), the couple needs a nudge.
 *  3. Skip couples where a gentle_reminder or automated_daily_reminder was
 *     already sent today (avoid over-notifying couples where a partner already
 *     manually nudged the other).
 *  4. Send FCM to all users in the couple + write to notification_queue.
 *  5. Record automated_daily_reminder/{docId} so this function is idempotent
 *     on re-runs.
