Closes #259
Summary
$app()renders a fixed close button that callsshiny::stopApp()when clicked. In a deployed app,stopApp()crashes the session for all users. This fix gates both the button (UI) and theobserveEvent(server) onrlang::is_interactive(), so neither exists when the app is running in a non-interactive context such as a deployed Shiny app.Verification
Run
querychat(ames)from an interactive R session — the close button appears in the top-right corner and clicking it returns the result as before. In a deployed app the button is absent.
