The Web composer now renders a request that declares the `plan-review` intent
as its own surface: the waiting-approval card language — amber "Plan review"
strip, the plan as the scrolling markdown body, the question as the card's
accessible name — over one decision row of Chat about it / Refuse / Approve.
Gone from that surface are the 1/1 pager, the numbered radio rows, the custom
answer row, and Skip/Submit, which made approving a plan read as sitting an
exam.
Approve and Refuse answer with the asker's own option labels and keep its
descriptions as tooltips; Chat about it cancels the request so the composer
returns and the user can simply say what they want. Copy is bilingual under the
existing `question` namespace.
The shape choice lives inside the single composer entry rather than a second
chain registration, so the two surfaces cannot race the same carrier, and
`planReviewOf` falls back to the generic flow for any request it cannot render
as a card — the client sits downstream of a wire boundary and every request
must stay answerable.
