Sydney RunkleandClaude Sonnet 4.5 99bc8bb9af feat(checkpoint/serde): serialize DiffDelta as 'diff' type tag ...

Add serde support for DiffDelta by implementing dump/load for the "diff" type tag.
This allows the checkpoint system to efficiently store delta objects by serializing
them as msgpack-encoded dicts with {"d": delta, "p": prev_version} structure.

The implementation uses runtime type checking to avoid circular imports and
leverages the existing msgpack ext hooks for proper deserialization of complex
types like LangChain messages.
