Instead, create an empty worktree on guests when a worktree is first *registered*, then update it via an initial UpdateWorktree message.
This prevents the host from referencing a worktree in definition RPC responses that hasn't yet been observed by the guest. We could have waited until the entire worktree was shared, but this could take a long time, so instead we create an empty one on guests and proceed from there.
We still have randomized test failures as of this commit:

Some types of messages, which entail state updates on the host, should be
processed in the order that they were sent. Other types of messages should
not block the processing of other messages.

This will make it possible for us to render their avatars. Previously we only had the user ids. During rendering, everything needs to be available synchronously. So now, whenever collaborators are added, we perform the async I/O to fetch their user data prior to adding them to the worktree.
This will allow us to use the word "collaborator" to describe users that are actively collaborating on a worktree.
