============================================================================ COUNTER SIGNAL (NUMERIC HELPER)

Signal specialized for numeric values with increment/decrement.

CounterSignal provides convenient methods for numeric operations.

Example:

class CartController extends NeuronController {
  late final itemCount = CounterSignal(0, min: 0, max: 99).bind(this);

  void addItem() => itemCount.increment();
  void removeItem() => itemCount.decrement();
}
