Live language switching reaches the desktop and manual

dhh merged omacom/omarchy#15326 into the quattro development branch on October 14, adding 50 languages for the menu, desktop and notifications, alongside manuals in 49 additional languages. The committed implementation also includes plural forms, localized numbers and mirrored panels for Arabic, Hebrew, Persian and Urdu. English remains the fallback.

The commit omacom/omarchy@84cfb93959f4 records per-user session language switching: newly launched apps receive the chosen language, while existing apps follow when restarted. During review, greptile-apps[bot] raised concerns about translated manual commands and links; dhh added comparisons against English and tests that deliberately corrupt a command block or chapter link. dhh also reported separating translation extraction from jobs holding write credentials and requiring human review when extraction changes executable code.
