demo: boot through the CGB BIOS + double-speed ROM in the README gif
spawn --bios shows the real power-on show (logo drop + splash) before
gbos boots; gbdemo resolves a bare --bios to the emulator's bundled
boot ROM by absolute path (the tmux pane cwd is wherever the user is).
The screen-synced waitfor absorbs the extra ~4s - only the first
prompt timeout got a bump. Regenerated with the double-speed kernel:
same demo, boots and scrolls visibly snappier.
