-// Add this helper function after the worker function
+// browseChildren browses the child nodes of the given node and queues them as tasks.
+// It only browses for variables and objects through hierarchical references.
+// The child tasks are queued with an incremented level and the current node's path and ID as parent.
+// Parameters:
+//   - ctx: Context for cancellation
+//   - task: The current node task being processed
+//   - def: Node definition containing path and ID information
+//   - taskChan: Channel to queue child tasks
+//   - taskWg: WaitGroup to track task completion
+//
+// Returns an error if browsing children fails
