Window.vertical_scroll is read-only in prompt_toolkit.
Use custom scroll_offset to track position and slice output lines.
- scroll_offset=0 shows newest content (auto-scroll)
- Page Up increases offset (scroll into history)
- Page Down decreases offset (towards newest)
- Home/End jump to top/bottom

- Use HSplit with filler + output to push content to bottom
- Output window uses dont_extend_height so it only takes needed space
- Empty filler expands to fill remaining space above

Instead of trying to scroll the window, just display the most
recent lines that fit on screen. Full history is kept but only
the last 50 lines are rendered.
