Preserve live Text selection when restoring Find focus

Keep existing reveal tickets and raw-input guards while separating focus restoration from cursor movement. This separable production patch is extracted from the Text workspace union verified by mounted red/green, full Windows gates and native replacement trials. The CBC-only intermediate tree was not separately built; the following contribution records exact tested union inputs and four-test integration guidance.
