ci(image): keep Claude Code 2.1.251; test(ceo-mode-routing): keep HOLD's own deferrals in scope before assessing its rigor decision

2.1.284 enables per-turn effort for claude-fable-5-1: in gate census
36626737820, 66 of 84 sessions ran longer than on 2.1.251 (+20% session time,
+32% thinking tokens) and 11 cases timed out on unchanged budgets.

HOLD SCOPE's 0G step asks its own defer/keep menu; the actor answered it
Defer and the assessment then judged that scope question as the rigor
decision. The actor now answers that menu Keep and assesses the next one.
