Checks if a resource is a published application system resource that should be hidden from users.

<p>Published application system resources are identified by:
- Folders that start with a dot (.) - these are hidden folders containing published app versions
- Files located within any folder that starts with a dot
- Examples: ".quick_app_name_0.0.1/", ".mind_map_name_0.0.2/document.json"

<p>These resources should only be accessible by applications (deployments), not by regular users.

@return true if this is a published application system resource that should be hidden from users
