Amos d1d28d6bb4 Session switch: land at the bottom instantly with the question dock open ...

- Chat now remounts per session (key={chat.id}): fresh StickToBottom,
  fresh DockOverlay (no cross-session morph from the previous shell
  height), fresh useChat.
- Conversation initial="instant" (was "smooth"): the mount scroll to
  bottom is a jump, not a slide.
- DockOverlay skips the pending-question scroll/expand effect for the
  session's INITIAL pending question (dock starts expanded; the initial
  scroll positions us) — previously it fired a second smooth
  scrollToBottom right after the library's initial scroll (the visible
  'pause, then the quiz pops and pushes everything up').
- The dock-variant fade/rise no longer plays for the session's opening
  variant; reserved for mid-session transitions.
Verified live: client-side switch settles at d=1px from the bottom within
one frame of content swap, dock open from the first frame, both
directions (quiz session, plain session).
