core-reminders: shared reminder-lead plumbing (ReminderUnit, override model + codec)

Pure-Kotlin module, drawn from the duplicate reminder logic in Agendula and
Calendula: the lead-time unit model (ReminderUnit / decomposeReminderMinutes),
the per-target override model (ReminderOverride + reminderLeadFor /
applyReminderOverride) and the stored-format codec (ReminderOverrideCodec).

The codec's separators are configurable so each app keeps its on-disk format
(Agendula stores id:minutes, Calendula id=minutes) without a data migration.

|--------|---------------|
| `core-time` | Pure-Kotlin date/time helpers: local-day windows (`DayWindow`) for smart-list logic and locale/zone-aware display formatting (`Instant.formatDate()` / `formatTime()` / `formatDateTime()`). No Android, no deps. |
| `core-reminders` | Pure-Kotlin reminder-lead plumbing: the lead-time unit model (`ReminderUnit`, `decomposeReminderMinutes`), the per-target override model (`ReminderOverride` + `reminderLeadFor` / `applyReminderOverride`) and the stored-format codec (`ReminderOverrideCodec`, separators configurable per app). No Android, no deps. Each app layers its own DataStore + string labels on top. |
