Module i18n 

Bilingual message layer for human-facing stderr progress (--lang en|pt, SQLITE_GRAPHRAG_LANG). Bilingual human-readable message layer.

The CLI uses --lang en|pt (global flag) or SQLITE_GRAPHRAG_LANG (env var) to choose the language of stderr progress messages. JSON stdout is deterministic and identical across languages — only strings intended for humans pass through this module.

Detection (highest to lowest priority):

1. Explicit --lang flag
2. Env var SQLITE_GRAPHRAG_LANG
3. OS locale (LANG, LC_ALL) with pt prefix
4. Fallback English
