Events

Subscribe with typed helpers or the bus.

val unsub = controller.onTextChanged { event ->
    // event.changes, event.kind, event.source
}
unsub()

controller.events.subscribe<CursorChangedEvent> { }

dispose() and leaving composition (via controller dispose only) clear the bus. The composable does not auto-clear events on detach.
