Feature summary (what you would like to be able to do and where):
On the article view, we should add a small "edit" link to the category list that will open VisualEditor and immediately launch the category-editing dialog.
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
VisualEditor has a category-editing feature. However, if someone scrolls down to the category list on an article and realizes they want to add/remove/edit the category list, it's not immediately obvious how to do so. They need to scroll back up and click an edit link, then once VE opens either know that they can click on the category list to trigger the dialog or find the "categories" item in the top-right hamburger menu.
There's a fairly popular gadget called HotCat that adds inline editing to the article-view category list, so this is clearly a feature that's desired. As I've suggested it, this wouldn't be quite as streamlined as HotCat because it'd still launch the entire VE experience, but that seems like the sweet spot for being a quick feature to implement.
Benefits (why should this be implemented?):
Categories are useful metadata, and it's currently more difficult than it needs to be to edit them.
