chore(i18n): 清理死代码 + 遗留 lang 文件 + 旧工具

## 删除的死代码脚本
- scripts/i18n_class_c.py (脚本自承'新架构下永远输出 0',纯防御性)
- scripts/full_migrate_i18n.py (其产出违反 CLAUDE.md 1.2 中文 key 铁律,已标 DEPRECATED)
- scripts/__pycache__/ (Python 缓存)

## 删除的旧 per-page lang 文件
- lang/zh-cn/<page>/<file>.js (140 个)
- lang/en-us/<page>/<file>.js (139 个)
- 共 279 个文件,运行时不再加载,0 个 key 被 .vue 调用(经 diagnose_keys.py 验证)

## 删除的备份和迁移表
- lang/_backup/ (git 已跟踪原文件)
- lang/_migration_map.json / lang/_migration-map.json (运行时不用)

## 删除的中间产物 JSON
- docs/i18n-rename-*.json (smart_rename 中间产物,已用完)
- docs/i18n-ambiguous.json / i18n-audit.json / i18n-call-rewrite.log /
  i18n-clean-dead.log / i18n-file-texts.json / i18n-page-titles.json /
  i18n-vue-extract.json (前一会话残留,无引用方)
- docs/i18n-{naming,shadow,strict}-audit.json (脚本会自动重新生成)

## 删除的 modular lang 文件
- lang/zh-cn/*.js / lang/en-us/*.js (20 个模块文件,内容是上一会话产生的死代码)
- lang/zh-cn/index.js / lang/en-us/index.js (聚合入口)
- lang/DEPRECATED.md (已不再相关)

## 删除的不成熟脚本
- scripts/check_perpage.py (诊断用,已完成)
- scripts/diagnose_keys.py (诊断用,已完成)
- scripts/smart_rename_i18n.py (v1-v3 都 bug,未修完)

## 现状
- lang/ 现在只有 zh-cn.js + en-us.js (单文件,运行时实际加载)
- 这两个文件已被 smart_rename 部分修复: camelCase → snake_case (8 个 key)
- 命名违规从 8236 降到 3505 (剩余都在单文件,可独立 commit 修复)
- 1362 个 orphan () 调用仍存在,详见 docs/i18n-handoff.md
