updated to newest libs

[amniskin]

We now have to call dml ref dump % before the dag message handler. The api for the user is still the same.

The type annotation change from Optional[Ref] to Optional[Union[Ref, Boxed]] indicates the field can now hold different types. This breaking change could confuse API consumers who expect a consistent type. Consider documenting this change or providing a migration guide.

Suggested change

	_message_handler: Optional[Callable] = None
	class Dag:
	"""
	Represents a DAG (Directed Acyclic Graph) for DaggerML operations.
	Migration Guide:
	----------------
	The type annotation for the `_ref` field has changed from `Optional[Ref]` to
	`Optional[Union[Ref, Boxed]]`. This means that `_ref` may now hold either a
	`Ref` instance or a `Boxed` instance. If you access `_ref` directly, you should
	check its type before using it:
	if isinstance(dag._ref, Boxed):
	value = dag._ref.value
	elif isinstance(dag._ref, Ref):
	# handle Ref as before
	...
	elif dag._ref is None:
	# handle None case
	...
	This change was made to support additional functionality. Please update your code
	accordingly if you rely on the `_ref` field.

The assertion logic x.rstrip() == "{" is unclear and fragile. It appears to be counting JSON objects by looking for opening braces, but this could break if the JSON format changes. Consider parsing the JSON properly or using a more robust method to count cache entries.

Suggested change

	assert len([x for x in cache_list if x.rstrip() == "{"]) == 2 # this gets us unique maps
	# Count valid JSON objects in the jsonlines output
	assert len([x for x in cache_list if x.strip() and _is_json_object(x)]) == 2
