goimports ships a hidden performance win: cmd/goimports now uses filepath.WalkDir instead of filepath.Walk, cutting one lstat per directory entry.

cmd/goimports switched from filepath.Walk to filepath.WalkDir [1]. Because the callback only needs the entry name and directory flag, the old Walk's per-entry lstat was pure overhead; WalkDir's fs.DirEntry avoids it. The change lands in golang/tools and does not alter goimports' output or command-line interface. Expect a modest speedup in directory traversal for large trees, with no behavioral change. The commit, reviewed on the Go Gerrit instance, is a small, safe dependency update for anyone tracking tools at tip.
