UI translation structure

UI translations are loaded from:

• src/i18n/common.json
• src/i18n/<lang>.json

The common.json layer contains strings shared across all languages to reduce duplication.

Debug translation structure

Debug strings are localized separately through:

• src/debug/i18n/common.json
• src/debug/i18n/<lang>.json

This keeps debug output independent from UI text.

Runtime selection

The selected UI language is stored in application settings and restored on startup.

Debug logging also performs system-language detection on Windows for console lifecycle logs.

Adding or updating a language

Recommended approach:

1. Add or update the UI JSON file in src/i18n/
2. Add or update the debug JSON file in src/debug/i18n/
3. Put truly shared strings in common.json
4. Keep user-facing text in JSON rather than hardcoding it in Rust
5. Verify UTF-8 encoding
