Find a better way to indicate deleted file, as opposed to new file created, as opposed to simply file not existing

File: extension.ts

The changes at peers include files they have created or deleted. These files show up in the Peer Changes SCM panel on the left-hand side of VSCode. However, we don't know if a file is created or deleted and we don't have a way to pull in those changes.

We need to think of a way to pull in entire-file operations from peers:

• when a file is deleted at peer
• when a file is renamed at peer
• when a file is moved to a different folder
• when a new file is created
