Signal<T> class

A typed signal that can be transmitted through cells.

Signals carry optional payload data and can be compared for equality. Used as the primary communication mechanism between cells.

Example:

// Example:
final numberSignal = Signal<int>(42);
final eventSignal = Signal<Map<String,dynamic>>({
  'type': 'click',
  'position': [100, 200]
});
