lucky_shop/scripts/i18n_audit.py

"""
i18n 审计单一入口 — 新增组件 / 新增翻译 / 拉取新 lang-bundle.json 后,
跑这一个脚本就能拿到体检报告。

Usage:
    python scripts/i18n_audit.py                       # 完整体检
    python scripts/i18n_audit.py --strict              # 出现真问题就 exit 1
    python scripts/i18n_audit.py --bundle <path>       # 指定 bundle 路径
    python scripts/i18n_audit.py --quiet               # 只打印问题摘要

工作内容:
  1. 静态扫描所有 .vue/.js 中的 $lang() 调用
  2. 与 lang-bundle.json 中的 leaf key 比对
  3. 检测占位符参数不匹配
  4. 检测 data() 中误用 $lang() 而未用 i18n-lazy mixin
  5. 检测 pages.json 中硬编码的 navigationBarTitleText
  6. 检测 bundle ↔ 本地 lang 目录的 drift
  7. 跑 verify-p2-keys.js 检查 P2 动态 key

为什么不用一个 shell 脚本:
  - 跨平台(Windows / macOS / Linux)统一入口
  - 自动汇总真问题 vs 误报,人工不再"翻报告"
  - 输出可被 CI 消费(--strict 模式)
  - 一处新增检查 = 加一个 .py 模块 + 在这里编排
