fix(coach): size the example opener to its text and keep it single-line

The ambient example opener was stretched to the full composer width, leaving
a large empty tail that read as broken. Size it to its text instead (capped at
the full width) and guarantee a single line: the question truncates with an
ellipsis on a narrow phone rather than wrapping or forcing a horizontal scroll.
