Avoids `as` casts
Removes unneeded imports

* Graph: double-click on a ref to check it out (similar to GKC)

* Renamed command type and function as requested in PR

* Removed cast to any

- Avoids polluting GitReference with graph specific data
 - Avoids Git tips ordering for proper group context
 - Reworks group context to merge with base context

- Hopefully ensures we will get build errors if the types change

Logs storage calls if they take too long

- fixes missing =: in searchRegex
- stops escape key from clearing-out the search input
- unifies padding on floating menus

* Added icons to hide and show ref nodes of the graph

* Added context menu option to hide branches

* Moved "Hide branch" option to the bottom of the menu

* Changes from code review, including

 - Renames some events/methods
 - Fixes context menus
 - Removed unnecessary debounce

* Validate the hidden refs against the real set of refs

* Typed "refType" property  and added to our d.ts file instead of using an string

* Created a "graph only" wrapper for the GitBranchReference rather than adding it to the general model

* Graph exposed event when hiding refs has been modified to accept a list of hidden refs

* Generic context menu when right-click on the overall ref to hide the whole ref.

* Commented hidden refs validation for v13, as it has too much performance impact. Will be solved after we launch v13 as tech debt
