v0.2.3

Added

• icon, and with it every widget's icon props: a name that isn't in the built-in set is drawn by Blade Icons (blade-ui-kit/blade-icons) when the app has it, so <x-widget.button icon-start="lucide-rocket"> or a dropdown item's icon="lucide-zap" work with any installed set, with the same classes and screen-reader handling. Built-in names still win, nothing new is required, and without Blade Icons an unknown name fails as before, its message now saying how to add one.
