fix(plan-ceo-review): name the mode preference command and the exact handoff line

auto-decide-preserved at 6fcb0981: the model never ran the preference check,
read 'check ... through the preamble' as already done, auto-selected 'per your
preference setting', and wrote 'Selected mode: HOLD SCOPE, auto-decided from
your tuned preference' instead of the AUTO_DECIDE handoff line. At 9a7a7e54 it
ran the check but wrote 'Decision: HOLD SCOPE is the review mode for ...'.
Neither matched the handoff template the observer recognizes. Name
gstack-question-preference --check at the point of use and say the handoff
begins with the exact matching line. Collapse the audit block's comment
padding to stay within the unchanged 80150-byte skeleton cap.
