setup flow: the dead dropdowns, save-never-sends, the pill hover

- The setup pickers opened invisible: React attaches a host element's ref
  AFTER descendants' layout effects, so MenuShell's mount-time place()
  measured a null anchor and gave up — the menu stayed hidden until a
  window resize re-ran place(). The stage-2 slot and thinking menus now
  anchor by anchorTestid (querySelector at place time, the settings-menu
  pattern) instead of the conditionally-attached triggerRef.
- Saving models NEVER auto-sends the queued message (owner ruling,
  2026-10-09): the draft waits in the composer and the learner sends it.
  The replay/draft-send calls removed from onDone in new-session, home,
  and chat; the dead force machinery removed from send/start/begin.
- The setup CTA pills get the app-wide hover language (hover:bg-accent +
  cursor-pointer) — hover:bg-muted was invisible because --muted and
  --card are the same #1c1c1c.
