+        Set the default bucket array capacity when creating a dictionary
+        without specifying a configuration. Recommended values: 16/32/64.
+        Higher values reduce resize operations but consume more memory.

+        Set the resize threshold as a percentage of capacity.
+        When element count >= capacity * (load_factor/100), the dictionary
+        automatically expands to prevent excessive hash collisions.
+
+        Common values:
+        - 50: Lower memory usage, more resize operations
+        - 75: Balanced (default)
