Design pass on the two-pane node updater:
- Taller card (a generous share of the window) so release notes get vertical
room and usually don't need to scroll.
- Wrap the version header + release notes in ONE rounded Material surface (drop
the divider between them); the notes markdown gets inner padding so it doesn't
touch the edges, and the header stays pinned while long notes scroll within.
- The verify note + install button now sit OUTSIDE that surface; the install
button is sized to its text instead of full width.
- Version cards: slightly smaller radius, accent bar removed, and the currently
installed (active) node is marked with a check on the right of its card.
- Footer: dropped the divider above Close and enlarged the Close button.
Verified 100% + 150%, dark + light.
