* Optimistically check if we need to do anything on a pull

Right now on a pull we always acquire a lock for a registry host. This is problematic because, for example, host can be pulling `ghcr.io/cirruslabs/macos-ventura-xcode:15-beta-2` image when a new request will come to pull `ghcr.io/cirruslabs/macos-ventura-xcode:latest` if needed.

In this situation, even though `ghcr.io/cirruslabs/macos-ventura-xcode:latest` is already cached and linked, `tart pull` will wait for a lock.

This change optimistically check if there is something to do at all before acquiring a lock.

* Fix linter errors
