fix(clarify): docstring — put options in choices[] only, never enumerate in question text

The model was enumerating options inside the question string (dead prose the UI
can't render as pickable rows). Schema description now spells out: choices[] is
REQUIRED for selectable options; question holds ONLY the question.
