feat(chat): answer the CLI's menus from the chat; Stop ends Thinking… (#74)

- A menu the CLI asks with (AskUserQuestion — one question or several,
  multiSelect —, a permission or trust prompt, Codex's approval, a
  first-start login menu) is read off the terminal under the chat
  (`parsePaneMenu`/`readRunMenu`) and shown in the prompt box's place as a
  card of buttons. A pick presses its digit (picks it, or ticks its box),
  Claude's unnumbered Submit row is reached with the arrows and Enter, and
  Cancel presses Esc. "Type something" opens a field in the card: its text
  goes in by the arrows, Ctrl+U over anything already typed there, a
  bracketed paste and Enter. That row presses no key — a second press of
  its digit typed the digit into the CLI's field ("44444…"). Keys verified
  on Claude Code 2.1.296 and Codex 0.161. AskUserQuestion fires no
  Notification, so a menu on screen also counts as waiting (live line, tab
  badge). Client only: no new route.
- #74: Esc before the model wrote anything puts the prompt back in Claude
  Code's input box and writes no "[Request interrupted by user]" line, so
  the transcript ended on the prompt and the chat read "Thinking…" for
  15 min. The chat's Stop now ends the live line until a newer transcript
  line arrives (matched by line, not by clock).
