Replace hasattr typemap checks with a None-defaulted ClassVar sentinel (#318)

Use a `None`-defaulted `ClassVar` for `TypedObject._typemap` and check
`cls._typemap is None` instead of `hasattr(cls, '_typemap')` in both
`_register_type` and `_resolve_type`. The `None` default preserves the
inheritance-sharing semantics: each polymorphic-base subtree lazily
creates and shares one registry dict, and mypy now narrows the attribute
to `dict` after the guards.
