Add cron expression support for recurring reminders using robfig/cron/v3. Changes: - Migration #2: ALTER TABLE reminders ADD COLUMN cron TEXT + next_fire_ts INTEGER - Reminder struct: add Cron and NextFireTs fields - scanReminder helper extracts full row including nullable cron - CreateReminder: accept optional cron param, store next_fire_ts = fire_ts - DueReminders: query on next_fire_ts instead of fire_ts - RescheduleReminder: new method — parse cron, compute next fire, update next_fire_ts or mark fired if no more valid times - Dispatcher: call RescheduleReminder for cron reminders, MarkReminder for one-shots (preserving existing behavior for ID=0 digest skip) - ReminderCompleter interface: add RescheduleReminder method - storeAPI adapter: forward RescheduleReminder - All callers updated: CreateReminder signature includes cron param - Tests: TestRecurringReminder (store), TestDispatchRecurringReminderReschedules - Existing tests updated for new signature

// Index i (1-based) is the user_version the step at migrations[i-1] brings the

// An empty slice is a clean no-op that leaves user_version at 0.
