Function flash_picker_message 

fn flash_picker_message(
    terminal: &mut Terminal<CrosstermBackend<Stdout>>,
    msg: &str,
) -> Result<()>

Render a single-line status page and pause briefly so the user can read it before the next picker step (or the chat) takes over the screen. Long messages now sit for 1.4 s — the previous 400 ms felt like “the page just flashed and disappeared.”
