Breaking changes

The format of messages has changed significantly since the last release, see https://github.com/pydantic/pydantic-ai/pull/232 and https://github.com/pydantic/pydantic-ai/pull/259
more messages/parts are added that before as a result of adding ToolReturnPart for each tool call, see https://github.com/pydantic/pydantic-ai/pull/184 and https://github.com/pydantic/pydantic-ai/pull/274
