refactor(breadcrumb): relocate Breadcrumb slice from entities to features

Breadcrumb is not a business aggregate — it is a scroll-tracking navigation capability (NavigationWrapper registers page sections into a store), so it belongs in the features layer, not entities. Move the whole slice and repoint its three widget consumers. entities/ now holds only Font, a true aggregate.
