Co-authored-by: aider (openai/gpt-5.2) <aider@aider.chat>

* refactor: 将 isinstance 检查改为元组、将默认模型值设为空字符串、将类型注解改为 Any 并导入

* refactor: 为 _serialize_job 增加返回类型注解 dict

* fix: 使用 cast 获取百度 AIP 的 msg 并对 psutil_addr 引入 type: ignore

Co-authored-by: aider (openai/gpt-5.2) <aider@aider.chat>

* refactor: 引入 _AddrWithPort 协议并替换 conn.laddr 的 cast
