The conversation pane had no scroll management at all - it opened at the top of history, ignored arriving messages, and offered no way back down other than dragging through long replies. - Opening a conversation lands on the newest message (the component is keyed by space, so mount = open) - A reader at the bottom stays pinned as new messages arrive; a reader up in history is left undisturbed - The moment the reader leaves the bottom, a floating "Jump to latest" pill appears above the composer; clicking it smooth-scrolls back and the pill hides itself again - The scroll region is a proper role="log" landmark; e2e seeds a dozen multi-line messages over real IPC, scrolls to the top, and drives the pill's appear -> click -> return-to-bottom -> disappear cycle
