ReadonlyNode<T> class abstract interface

Interface for readonly reactive nodes.

ReadonlyNode represents a reactive value that can be read and tracked as a dependency, but cannot be modified. It provides lifecycle management through disposal.

Example:

final count = Signal(0);
ReadonlyNode<int> doubled = Computed(() => count.value * 2);
print(doubled.value); // OK
// doubled.value = 6; // Compile error
