* support libraryItems promise for `updateScene()` and use `importLibrary`
* fix typing for `getLibraryItemsFromStorage()`
* remove `libraryItemsFromStorage` hack
if there was a point to it then I'm missing it, but this part will be rewritten anyway
* rewrite state handling
(temporarily removed loading states)
* add async support
* refactor and deduplicate library importing logic
* hide hints when library open
* fix snaps
* support promise in `initialData.libraryItems`
* add default to params instead
