prompt: notepat shortcut button next to the version button
Add a TextButtonSmall labelled "notepat" to the right of the commit
button on the prompt curtain, with a tiny 7x5 piano icon drawn over
the leading whitespace. Plum/purple color scheme distinguishes it
from the neutral version button. Push handler calls jump("notepat")
with the standard down/push/cancel sound pattern; the button is
wired into both keyboard-lock hit-zone checks and hides alongside
the commit button when version info is unavailable.
