Remove the menu fold

The header menu no longer folds into a ☰ button: the nav_fold and
nav_fold_label options, Layout.Fold/BurgerAt, the burger markup and its
checkbox, the fold rules in blog.css and the measuring script on the
public page are gone, and the Design tab's preview only sizes its frame
again. The public page runs no script of its own once more.

-/* menu fold (theme nav_fold): the header menu becomes a button when its links
-   do not fit. The hidden (offscreen, still focusable) checkbox before the
-   header's blocks is the open/closed state; the label is the button, at the
-   right of the title or logo block above the menu (.has-burger on that
-   block), or in the bar when nothing is above it. Which state applies:
-   .nav-folded is set by the page's script when a link wraps, .nav-auto is the
-   no-script fallback (folded on phones only) the script removes; the two
-   blocks below must stay identical. */
