 * pi extension factory, shared by both hosting shapes:

 *   - src/tui.ts passes it to coding-agent's main() as an inline extension, adding
 *     GUI-mode extras (tool narrowing + system prompt) on top
 * Driver/strategy come from env (PI_GUI_DRIVER / PI_GUI_STRATEGY) unless a resolved
 * profile is injected.
