Merge store listing (#285)

Paged and Split now page like the week and day views; Split keeps its
vertical expand drag, now vertical-only beside the pager, and the pane
follows the grid's row count mid-swipe. The old trigger swipe and slide
transition are gone with their last callers.

Closes #336

+Overlays leave through floret-kit's `predictiveBackExit`, so a committed back
+gesture finishes from its scaled preview.
+
+### Switching views (#184)
+
+- **One focused date.** `CalendarHost` owns a `ViewFocus` (`LocalViewFocus`)
+  that every view opens on and carries along. A view *reads* it once, on
+  entry, synchronously (`EnterOnFocus` before it reads its own position, so
+  its first frame is already on that date), and *writes* it only when the user
+  moves — a pager settling (`focusOnPage` keeps the date's place in the page),
+  a jump, Today, a tapped day, the agenda's top row. Writing on entry would
+  drift the date on every round trip.
+- **Three screens, not five.** The host's `AnimatedContent` is keyed on
+  `ViewScreen` (month, timeline, agenda), not on the view: day, multi-day and
+  week are one `TimelineScreen` with a `TimelineKind` each and a view model
+  each. Keying the three on one `contentKey` instead would still replay the
+  enter transition on every switch among them.
+- **Timeline ↔ timeline resizes in place.** `ColumnGeometry` places every
+  column (header cell, all-day bar, day column) in the layout pass; a switch
+  swaps the pager for a frame over both pages' days, each column lerped
+  between its slot on the one page and the other — a day the page doesn't
+  show carries on at its pitch, off screen, which is what slides it in or
+  out. Blocks sit in their column as shares of its width (`LaneColumn`), so
+  nothing recomposes per frame. The frame starts and ends exactly as the two
+  pages lay out, so the pagers either side hand over without a jump.
+- **Across screens, what both show morphs.** Inside a `SharedTransitionLayout`,
+  an event shown in both views travels from its old bounds to its new ones,
+  keyed per occurrence *and* per day it is drawn from (`ViewMorphKey`); only a
+  pager's settled page carries the tags. The drawer, top bar and FAB are not
+  per screen: CalendarHost draws them once, above the switch, from what the
+  screen on show publishes (`PublishChrome` in `CalendarChrome.kt`), so a
+  switch only changes what they say.
 A tapped reminder notification routes through `MainActivity` (`singleTop` +
 `onNewIntent`) as an external detail key that `CalendarHost` consumes
 exactly like an event tap.

+Calendula — праграма-каляндар з адкрытым зыходным кодам для Android. Яна працуе непасрэдна з сістэмным пастаўшчыком календароў, таму ўсё, што сінхранізуецца з вашай прыладай (Nextcloud праз DAVx5, Google, лакальныя календары, падпіскі WebCal), з'яўляецца ў Calendula, а вашы змены сінхранізуюцца назад тым жа шляхам.
+
+Ёсць віды «Месяц», «Тыдзень», «Дзень» і «Парадак дня». Вы можаце ствараць, змяняць і выдаляць падзеі, у тым ліку паўтаральныя, і задаваць паўтор з гатовых варыянтаў або сваімі правіламі. Пры змене паўтаральнай падзеі вы выбіраеце, ці датычыцца змена толькі гэтай падзеі, яе і ўсіх наступных або ўсёй серыі.
+
+Calendula паказвае напаміны пра падзеі ў выглядзе апавяшчэнняў. Націсніце на апавяшчэнне, каб адкрыць падзею.
+
+Калі ўключыць гэту функцыю, Calendula пакажа і дні нараджэння, гадавіны ды іншыя даты вашых кантактаў. Кантакты чытаюцца на прыладзе, нікуды не адпраўляюцца і не змяняюцца. Calendula капіюе даты ў лакальныя календары, якімі кіруеце вы.
+
+Дызайн усюды выкананы ў Material 3 Expressive: дынамічныя колеры, выразная анімацыя і формы.
+
+У Calendula няма тэлеметрыі, аналітыкі і доступу да сеткі. Вашы даныя не пакідаюць прыладу.
