This change moves to our ultimate approach of diagnostics the snapshot on every file change, instead of carefully picking which files and packages to diagnose. Analyses are shown for packages whose files are open in the editor. Reverse dependencies are no longer needed for source.Diagnostics because they will be invalidated when the snapshot is cloned, so diagnosing the entire snapshot will bring them up to date. This even works for go.mod files because all of workspace-level `go list`s will be canceled as the user types, and then we trigger an uncancellable go/packages.Load when the user saves. There is still room for improvement here, but it will require much more careful invalidation of metadata for go.mod files.
