- 更新了`uni_message_sender.py`，使用`MessageEnvelope`来发送消息，取代了之前的`MessageSending`结构。 - 引入了`send_envelope`函数，通过改进日志记录和错误处理来简化消息发送流程。 - 修改了`HeartFCSender`以直接处理`MessageEnvelope`，确保与新消息结构的兼容性。 - 重构了`default_generator.py`，以构建`MessageEnvelope`而不是`MessageSending`，从而增强了消息构建逻辑。 - 调整了`utils.py`中的效用函数，以使用`DatabaseUserInfo`来处理用户信息。 - 更新了`send_api.py`以构建和发送`MessageEnvelope`，从而改进了消息分发逻辑。 - 从插件系统中移除了已弃用的`MaiMessages`类，清理了未使用的代码。 - 增强了`napcat_adapter_plugin`以适应新的消息结构，确保消息的正确处理和发送。 - 对代码进行整体清理和整理，以提高可维护性和可读性。
