Fully defaulted Destructured objects' defaults do not apply

@dataclass
class Foo:
    color: Annotated[str, cappa.Arg(long=True, default=Env("FOO"))]

@dataclass
class Args:
    attrs: cappa.Destructured[Foo]

def test_destructured():
    with patch("os.environ", new={"FOO": 'blue'}):
        test = parse(Args)

    assert test == Args(attrs=Foo('blue'))

this being because destructured handling manipulates parsing/action handling and makes it happen outside the normal recursive mapping phase. It feels ideally destructured mapping should mirror subcommands, so that when it's encountered naturally during mapping, the child object's mapping natively recurses into it
