- Updated arrow key navigation to include user message when applicable
- Adjusted active index calculation to account for user message presence

* - fix the logic for slicing matching options to maxOptions

slice(0, Math.max(0, maxOptions ?? 0) || Infinity) treats 0 as falsy and shows all options. Honor 0 explicitly

-      {#each matchingOptions.slice(0, Math.max(0, maxOptions ?? 0) || Infinity) as
+      {#each matchingOptions.slice(0, maxOptions == null ? Infinity : Math.max(0, maxOptions)) as
         option_item,
         idx
         (duplicates ? [key(option_item), idx] : key(option_item))
       }

- introduce a new `selected` constant to streamline the selection state handling
- adjust aria-selected attribute to reflect the selected state accurately
- enhance unit tests to ensure correct behavior with various maxOptions values
