refactor(core): 提升类型安全性并添加配置空值检查

此提交在核心模块中引入了多项改进，以增强类型安全性和健壮性，主要通过为类型提示添加 `cast` 并在访问 `global_config` 属性前进行空值检查实现。

主要改动包括：
- **类型安全**：在 `message_handler.py`、`unified_manager.py` 和 `napcat_adapter` 的消息处理器中使用 `typing.cast` 来解决类型不一致问题并提高静态分析的准确性。
- **配置空值检查**：在 `message_handler.py` 和 `message_processor.py` 中添加对 `global_config` 及其嵌套属性的检查，以防止在应用启动或配置加载过程中出现 `NoneType` 错误。
- **内存管理提示**：优化了 `unified_manager.py` 中内存判断器的提示，使其在获取长期记忆时更加保守，从而提升简单交互的性能。
- **Napcat 适配器**：新增了视频处理的配置选项以及回复行为。同时改进了消息解析逻辑的鲁棒性。- **消息处理器**：重构了 `_process_message_segments` 及相关函数，移除了未使用的 `message_info` 参数，从而简化了函数签名。
