Walkthrough

The changes extend the public function signatures for Unarchive and Archive to accept a new dirMode parameter of type fs.FileMode, allowing directory permissions to be configurable. Both functions are updated to use this parameter during directory creation instead of hardcoded constants. Call sites in tests and HTTP handlers are updated to pass the new parameter.
