This PR adds a REST API to the collab server for searching and
downloading extensions. Previously, we had implemented this API in
zed.dev directly, but this implementation is better, because we use the
collab database to store the download counts for extensions.

Over time, I think we may end up having multiple services, so it seems like a good opportunity to name this one more specifically while the cost is low. It just seems like naming it "zed" and "zed-server" leaves it a bit open ended.
