"""core/config_paths.py —— 统一的配置文件路径解析与容错加载（P0-01 新增）
|
||
|
||
所有配置读取入口必须经过本模块，不得在别处直接定位 data/config.json：
|
||
|
||
1. 环境变量 HAOCODE_CONFIG_FILE 优先级最高（自动化测试用它指向临时文件）；
|
||
2. 未设置环境变量时才回落到项目内 data/config.json（锚定 core/ 目录，不受 CWD 影响）。
|
||
|
||
行为约定（REPAIR_BACKLOG P0-01 硬约束）：
|
||
· 路径解析与加载过程只在出错时输出可见警告（只含路径与错误类型，不含配置内容）；
|
||
· 缺失 / 损坏 / 非 JSON 对象 → 返回安全空 dict 继续，不抛异常、不阻断
|
||
不需要该配置的源码路径；
|
||
· import 本模块时不打印、不复制、不迁移任何配置内容。
