Function TestVerifyNudgeYieldsToEmptyReply

internal/tui/tui_test.go:2124–2142

TestVerifyNudgeYieldsToEmptyReply: an empty newest assistant message is the empty-reply nudge's domain even on a substantial turn: the verify nudge must not pre-empt it (its note re-grounds a summary that doesn't exist).
