17c9aa1819 Remove ShareWorktree message 
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:

f2b4a0665f Fix integration test verifying the rename behavior 
Specifically, the test now ensures that the host's worktree observes a/file1's
change event *before* the rename occurs, otherwise when interpreting the change
event it will mistakenly think that the file has been deleted (because its path
has changed) and will subsequently fail to detect the rename, causing the test
to fail.

are no longer generic over an anchor type.

d4fe1115e7 Use an unbounded channel for peer's outgoing messages 
Using a bounded channel may have blocked the collaboration server
from making progress handling RPC traffic.

There's no need to apply backpressure to calling code within the
same process - suspending a task that is attempting to call `send` has
an even greater memory cost than just buffering a protobuf message.

We do still want a bounded channel for incoming messages, so that
we provide backpressure to noisy peers - blocking their writes as opposed
to allowing them to buffer arbitrarily many messages in our server.

This isn't perfect but we'll retain up to 10 old versions just in case there

but we're concerned about diagnostic reporting racing with code action
resolution.
