feat(edit): conflict dialog on save + store metadata refresh (v2.0)

No locking (plan 03, decision 5): openForEdit keeps an EditSnapshot — the
prefilled form plus the raw Events-row times, which the form itself can't
see (it derives its times from the tapped occurrence, so an externally
moved event would otherwise stay invisible). Right before writing,
performSave re-reads the event and compares snapshots: a mismatch parks
the save in SaveUiState.AwaitingConflict carrying the already-chosen
recurring scope, and the dialog offers overwrite / discard / cancel
(OptionCard style). Overwrite still writes only dirty fields, so external
changes to untouched fields survive either way. A deleted event lands in
SaveUiState.Gone — an informational dialog that closes form and detail.
Fields the form can't write (attendees, status, self response, reminder
methods) are excluded from the comparison so sync noise can't fake a
conflict. The load-time zone is pinned in the EditTarget so a device
timezone change mid-edit can't either.

Store metadata: F-Droid descriptions (DE+EN) and the README stop claiming
read-only and now describe write support and reminder delivery. New
fastlane phoneScreenshots (6 per locale: week/month/day/detail/form/
reminder onboarding), captured on-device against demo-only calendars.

Tests: EditSnapshot equality (unchanged event, field change, row-time move
the form can't see, non-writable changes stay quiet).

Calendula ist eine moderne, quelloffene Kalender-App für Android. Sie
arbeitet direkt auf dem System-Kalender-Provider — jede Quelle, die mit
deinem Gerät synchronisiert ist (Nextcloud über DAVx5, Google, lokal,

synchronisieren auf demselben Weg zurück.
Termine erstellen, bearbeiten und löschen — auch wiederkehrende, mit
wählbarer Reichweite (nur dieser Termin / dieser und alle folgenden / ganze
Serie) und einem einfachen Wiederholungs-Picker. Erinnerungen stellt
Calendula selbst als Benachrichtigung zu — ein Tipp darauf öffnet den
Termin.
Der Unterschied liegt im Design: echtes Material 3 Expressive durchgehend,
mit Dynamic Color, expressiven Animationen und neuen Shape-Sprachen.
V1 ist read-only. Erstellen, Bearbeiten und Löschen von Events kommt mit V2.
Datenschutz: keinerlei Telemetrie, kein Tracking, kein Netzwerkzugriff — deine

The differentiator is the design: real Material 3 Expressive throughout, with
dynamic color, expressive motion, and expressive shapes.
Create, edit and delete events, including recurring events with scoped
changes (only this event / this and all following / the whole series) and a
simple repeat picker. Calendula also delivers your event reminders as
notifications — tap one and you're on the event.
V1 is read-only. Event creation, editing, and deletion are planned for V2.
