test: supply the split-overflow fixture's HOLD SCOPE mode as a prerequisite

The split actor always answered 0E's mode question with HOLD SCOPE. The
skill skips that question on an explicit choice, so the fixture now states
it and the attempt starts at the five candidate decisions (about 1.5 min
earlier in run 36385945043). Candidates, actor policy, floor and semantic
evaluation are unchanged; the fixture test pins the supplied choice.
