- Add 6 locales (en-US source + ru-RU, de-DE, fr-FR, es-ES, zh-CN)
matching the patcher's WPF UI; full .po catalogs incl. plural forms.
- Language selector in the left settings drawer; persist choice and
auto-detect from navigator language on first load.
- Load .po directly via @lingui/vite-plugin (drop the compile step);
gitignore generated catalog .js as build artifacts.
