Updating Comfy / custom nodes

When the target Comfy changes:

1. Snapshot /object_info again
2. Recapture comfy.lock.json
3. Regenerate typed nodes
4. Rebuild IR from ir.build.ts
5. cwf pack / validate
6. Commit. CI git diff --exit-code should be green because you updated the artifacts on purpose.

If you skip codegen, g.add will not know new classes and compile against live defs will throw E_UNKNOWN_NODE_TYPE.

If you skip the lock update, you get E_LOCK_DRIFT warnings forever.

Do not "fix" drift by editing hashes.
