Remove the positional `typ` parameter from `DeltaChannel.__init__`. The type is now injected automatically from the `Annotated` outer type in `_is_field_channel` (matching how `BinaryOperatorAggregate` receives its type). `copy()` and `from_checkpoint()` propagate `self.typ` explicitly. Test helpers updated to use `_get_channel` with the proper `Annotated` path.
