The "Event" name was overloaded — the store-mutation type lived
right next to Nostr Event, so StoreEvent.Insert(event: Event) read
awkwardly. Renaming to StoreChange disambiguates and matches
reactive vocabulary ("store changes").
- StoreEvent → StoreChange (file, sealed type, all references).
- ObservableEventStore.events → ObservableEventStore.changes.
- Internal field _events → _changes.
- KDoc cross-references updated.
Case names (Insert, DeleteByFilter, DeleteExpired) unchanged. All
240 store + projection + interner tests still pass.
