- 修复背景：在配置 parser_bili_video_codes 环境变量（如 ["hev", "av01", "avc"]）时，因 bilibili_api 中 VideoCodecs 枚举成员值为元组类型，导致 Pydantic 默认枚举校验报 ValidationError。
- 解决方案：在 Config 模型中增加 parser_bili_video_codes 的前置字段校验器（@field_validator(mode="before")），支持将字符串列表、JSON 数组及逗号分隔字符串自动转换并映射至对应的 VideoCodecs 枚举成员。
- 影响范围：仅影响 config.py 中 parser_bili_video_codes 配置项的反序列化与兼容解析。
