build() always finished by calling ui_state.set_root(), which is right for a window that *is* the transcript screen and wrong for a caller embedding it beside something else (the desktop app's session list). build_tree() is build() minus that last step, returning the widget tree instead of planting it; build() is now one line on top of it, so nothing else changes for existing callers.
