    "@types/semver": "7.7.1",
    "@types/watchpack": "2.4.4",
-    "next": "16.0.10"
+    "next": "16.1.6"


I think merging this would break 16.0 type compatibility with workflow. so new workflow versions will require you to use workflow >16.1

without this change, it looked like CI was failing: https://github.com/vercel/workflow/actions/runs/21695038244/job/62563367028?pr=944

This is alright, peerDependency is the one that controls what versions users can have installed.
