fix: watch for structural changes on objects and arrays

[anthonyshort]

When doing something like this:

effect(() => {
  state.todos.forEach((todo) => console.log(todo));
});

I'd expect it to run when I add/remove items from the todo list. This change adds this in a pretty naive way by looking to see if the keys have changed on objects and arrays.

Nice catch. Let me take it over as I think there should be a better implementation.
