Subject: [PATCH] fix(claude): keep a numbered list above a question from
 hiding its card

The Claude question parser scanned up to 64 lines above the "Enter to
select" hint and required every numbered row in that window to run 1..N.
When the assistant's reply above the question ended in a numbered list,
those items were read as rows too (37., 38., ... ahead of the real 1.),
the check failed, and a short question that fits the screen got no card.

Take only the current run of rows: the contiguous run that ends at the
last row above the hint and counts back down to 1. Numbered lines above
that 1. are ignored. The question text and the answer path are unchanged.

The transcript-ask parser already finds the real rows: it slides a window
that must number 1..N, match the transcript's labels in order and end in
"Type something." and "Chat about this", so a list above the frame cannot
complete a match. A test pins that.
