When the daemon starts after being offline, multiple due reminders
would fire simultaneously as separate notifications. Now a single
digest reminder is dispatched instead, summarizing all pending items.
- New collapseReminders() helper in gather.go: if 2+ reminders are
due, marks originals as fired and returns one synthetic reminder
(ID=0) with a combined JSON payload.
- Dispatcher skips MarkReminder for ID=0 (synthetic digest).
- All loop and delivery tests pass.
Adds QuietHours config section (start/end as HH:MM local time). The loop's
gatherer checks the window each tick: if now falls within [start, end), the
State.QuietHours flag is set to true regardless of the config fact (which
the voice toggle writes independently). Both sources activate quiet —
schedule AND toggle.
Handles midnight-crossing windows (23:00-08:00). The gate already reads
State.QuietHours for care nudge suppression — no gate change needed.
