feat(engine): Report the selected text; remember recently used fonts

type.selectionAttrs reports the start of the selected text on one line
(`selectedText`, up to 60 characters), for previews such as the font
menu's Selected Text sample. The preferences keep `recentFonts`, the
fonts last picked in the font menus.
