This change adds support for returning versions along with file URIs, so that the client can know when to apply changes. The version is not yet propagated along to the internal/lsp/cache package, so this change will have no effect (VS Code ignores a version of 0 and still applies the changes). A few minor changes made in the rename code (to remove the view parameter). Some minor staticcheck fixes.
