* Python: Add allowed_checkpoint_types support to CosmosCheckpointStorage (#5200) Add allowed_checkpoint_types parameter to CosmosCheckpointStorage for parity with FileCheckpointStorage. This ensures both providers use the same restricted pickle deserialization by default. Changes: - Accept allowed_checkpoint_types kwarg in __init__, stored as frozenset - Convert _document_to_checkpoint from @staticmethod to instance method - Forward allowed_types to decode_checkpoint_value on all load paths - Update class docstring to describe the new parameter - Add tests covering built-in safe types, app type opt-in/blocking, and all load paths (load, list_checkpoints, get_latest) - Add changelog entry noting the breaking behavior change BREAKING CHANGE: CosmosCheckpointStorage now uses restricted pickle deserialization by default. Checkpoints containing application-defined types will require passing those types via allowed_checkpoint_types.
