Amos cd789c11b1 UI iteration 3: question dock — pending questions morph the composer blob
- A pending quiz/ask now REPLACES the chat composer: one persistent
  rounded-2xl shell in the transcript overlay swaps contents (composer ↔
  question ↔ collapsed bar), never remounting — the structure a future
  grow-morph animation needs.
- Unified bottom row inside the question: the note field (select modes),
  the answer field (text-mode asks), or the Other text — one field, one
  'Submit answer' button, Enter submits.
- Collapse on scroll: uses useStickToBottomContext — scroll up and the
  dock folds to a slim bar (kind chip + LaTeX-flattened question teaser +
  'tap to answer'); click scrolls to bottom and re-expands. The expanded
  form stays mounted-hidden so a half-made selection survives.
- Pending/streaming tool parts no longer render inline; answered parts
  land in the transcript as graded cards on submit. Question generation
  shows a shimmer in the shell.
- Composer back to pure chat (no mode machinery); quiz-card.tsx and the
  pendingText/registerSubmit bridge deleted; render tests re-pointed at
  the dock (wrapped in StickToBottom).

Verified live: docked quiz submit (note+selection), ask-text Enter
submit, collapse/expand with selection survival, bar teaser text.
