Reviews before merge:
- EventInterner: drop stale "used by Event.fromJson" reference (we
reverted that earlier). Tighten the class doc.
- ObservableEventStore: collapse the 30+ line class KDoc + duplicated
StoreChange description into one focused doc each.
- EventStoreProjection: trim the 60+ line class doc; reactive
semantics live on the project() extension. Add explicit caveat
about in-place addressable updates not re-evaluating filter
membership.
No behaviour change. All cache + store + projection tests pass.
