fix: 修复ComfyUI SDK的cargo check和clippy警告

- 修复ComfyUIError中WebSocket变体过大的问题，使用Box包装
- 添加自定义From实现处理Box包装的WebSocket错误
- 修复所有格式化字符串警告，使用内联格式化
- 移除无用的类型转换（reqwest::Error::from）
- 修复代码质量问题：
  - 简化if语句嵌套
  - 使用?操作符替代显式错误处理
  - 优化map迭代方式
  - 使用is_some_and替代map_or

修复内容:
- 44个clippy警告全部解决
- 所有测试通过
- cargo check --lib 无错误无警告
