test(ceo-mode-routing): accept the skill-mandated Note form and Recommendation reason as HOLD posture

HOLD Defer/Keep briefs must use 'Note: options differ in kind' (preamble),
but the answered-HOLD path demanded a Completeness score, rejected a
one-line Net with a semicolon, and read posture only from ELI10. The rerun's
brief applied HOLD SCOPE in its Recommendation reason. Revert the
ineffective 'always'/'handoff chat' wording: two runs still skipped the
mode handoff.
