chore: draw week numbers from floret-kit isoWeekNumber; bump kit pin

The Week and Month grid headers each inlined the same ISO-week-number
computation. Replace both with the new shared
core-time LocalDate.isoWeekNumber(), and bump the floret-kit submodule
pin (5a576c4 -> cded442) to the commit that adds it.

@@ -5,6 +5,38 @@ All notable changes to this project will be documented in this file.

+## [2.14.0] — 2026-07-06
+
+### Added
+- Restore events from a backup file. The backup section of Settings can now read
+  events back **in** from an `.ics` file, not just write one out: pick a file,
+  choose which calendar to import into, and Calendula adds the events — skipping
+  any that are already there and telling you how many it skipped. Export gained a
+  per-calendar selector at the same time, so you can back up just the calendars
+  you pick instead of everything at once ([#32]).
+- Week numbers in Month view. A new **Week numbers** setting (off by default)
+  adds a slim gutter down the left of the Month grid showing the calendar-week
+  number for each row, sized to match the day cells. Handy if you plan or refer
+  to dates by week number ([#25]).
+- Tap a date header to open that day. In Week and Agenda view, tapping a date
+  header now opens that date in Day view — the same drill-in that Month view and
+  the agenda widget already offered, so every view behaves the same way. It makes
+  jumping to a specific day quicker: switch to Week, swipe to the week you want,
+  then tap the date to open it. Thanks to @ptab for the suggestion ([#37]).
+- An early Simplified Chinese translation. Calendula has started speaking
+  Simplified Chinese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  It is still an early effort, so many parts of the app show in English until it
+  fills out — you can already pick it under Settings → Language or in Android's
+  per-app language settings. Thanks to
+  [zh-cn](https://weblate.dev.jeanlucmakiola.de/user/zh-cn/) for getting it
+  started; help finishing it is very welcome.
+
+### Changed
+- Long event titles wrap in the edit screen. When editing an event, a long title
+  now wraps onto multiple lines instead of being clipped to a single line, so you
+  can see and edit the whole thing ([#33]).

+ * Calendula's theme: the family's [FloretExpressiveTheme] machinery — dynamic

+ * (spring choreography without the overshoot) — fed with Calendula's own

+ * [CalendulaDarkFallback]) and a [typography] that defaults to
+ * [CalendulaTypography] but is overridable for the user's custom-font choice
+ * (issue #19).
  *
- * The Settings screen overrides darkTheme, dynamicColor, and typography; the
- * bare defaults (used by the crash screen) just follow the system.
+ * The mechanics live in floret-kit's identity module; the look stays here, so a

+### Added
+- Restore events from a backup file. The backup section of Settings can now read
+  events back **in** from an `.ics` file, not just write one out: pick a file,
+  choose which calendar to import into, and Calendula adds the events — skipping
+  any that are already there and telling you how many it skipped. Export gained a
+  per-calendar selector at the same time, so you can back up just the calendars
+  you pick instead of everything at once ([#32]).
+- Week numbers in Month view. A new **Week numbers** setting (off by default)
+  adds a slim gutter down the left of the Month grid showing the calendar-week
+  number for each row, sized to match the day cells. Handy if you plan or refer
+  to dates by week number ([#25]).
+- Tap a date header to open that day. In Week and Agenda view, tapping a date
+  header now opens that date in Day view — the same drill-in that Month view and
+  the agenda widget already offered, so every view behaves the same way. It makes
+  jumping to a specific day quicker: switch to Week, swipe to the week you want,
+  then tap the date to open it. Thanks to @ptab for the suggestion ([#37]).
+- An early Simplified Chinese translation. Calendula has started speaking
+  Simplified Chinese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  It is still an early effort, so many parts of the app show in English until it
+  fills out — you can already pick it under Settings → Language or in Android's
+  per-app language settings. Thanks to
+  [zh-cn](https://weblate.dev.jeanlucmakiola.de/user/zh-cn/) for getting it
+  started; help finishing it is very welcome.
+
+### Changed
+- Long event titles wrap in the edit screen. When editing an event, a long title
+  now wraps onto multiple lines instead of being clipped to a single line, so you
+  can see and edit the whole thing ([#33]).
