fix: ctrl k not showing navigation items + improve ai button by making it an item in the menu (#6132)

* Fix missing navigation after migration to svelte 5 of ctrl k search

.includes doesn't work anymore because the items inside the array are
treated as state, and thus svelte wraps them with a Proxy thing

* Change ask ai to be a menu item

* Remove comment
