Convenience extensions

Extensions construct ordinary observable wrappers; they do not introduce a second reactive model.

final count = 0.obs();
final names = ['Ada'].asObservable();
final selected = <String>{}.asObservable();
final prices = {'Notebook': 24}.asObservable();
final request = Future.value(42).asObservable();
final signal = Stream.value(1).asObservable();

IntExtension, DoubleExtension, BoolExtension, and StringExtension wrap primitive values. ObservableListExtension, ObservableSetExtension, and ObservableMapExtension wrap collections. ObservableFutureExtension and ObservableStreamExtension wrap async sources. ObservableBoolExtension supplies boolean operations. Check their signatures for supported names, contexts, and options.

An extension call creates a wrapper; it does not change the original object's type or convert everything reachable from it. Keep the wrapper in the owning store instead of constructing it during every build.
