[Feature Request] AskUserQuestion option descriptions truncate on mobile, hiding key differentiators

Bug Description
Title: [Mobile] AskUserQuestion option descriptions truncate to ~2 lines, hiding the differentiator

Type: Feature request / UX

What happens: On the Claude Code mobile app, the option descriptions in a multiple-choice question (AskUserQuestion) are clamped to ~2–3 lines and hard-truncated with an ellipsis. When the distinguishing detail is at the end of the description (a common, natural way to phrase trade-offs), it's cut off — e.g. "…Simplest, mat…" vs "…Immune to scanner bur…". The choice becomes unreadable without switching to desktop.

Expected: The option box should auto-expand vertically to fit the full description text (or be tap-to-expand / scrollable), so no content is lost on mobile.

Impact: Forces a context-switch to desktop to read choices; risks picking the wrong option when the differentiator is hidden.
