Fix game crash: revert KeyMap to minimal runtime set, move full translation to extraction tool

- Revert ObjExtensions KeyMap to pre-existing 20 entries only
  (prevents runtime crashes where old code references Japanese keys)
- Add complete EnglishNameMap to extraction tool for directory naming
- Extraction produces English directories, game uses minimal MigrateKeys
- original_key in YAML correctly captures pre-migration Japanese key
