fix(plan-ceo-review): restore experience-first expansion framing, require the mode handoff, skip pacing menus

Census 36597762183: both mode-routing runs logged provenance and moved on
without the mandated handoff chat; the EXPANSION run asked an unauthorized
batch/narrow pacing menu instead of the first per-addition question; the
expansion-energy proposals led with the spec because v1.87.6.0 dropped
'lead with the felt experience'. The HOLD review detector also rejected a
decision whose grounding line named no plan file although the owned source
Read binds it.
