Keep late background progress out of a newer conversation turn

Why: Completion or progress from an earlier task could appear in the process of an unrelated newer answer.

Evidence: The new ownership regression fails before the guard and passes afterward; the frontend suite, TypeScript and unchanged export gate pass.

Impact: Project child progress only into its originating live turn while still reconciling background results.
