THEN Refactor message chunk classes to avoid multiple inheritance. Make BaseMessageChunk inherit from BaseMessage directly, then have specific chunk classes (e.g., HumanMessageChunk) inherit only from BaseMessageChunk. Alternatively, use composition by delegating to a BaseMessageChunk instance.

class BaseMessageChunk(BaseMessage):
    pass

class HumanMessageChunk(BaseMessageChunk):
    pass
