[Feature Request] Translate built-in plugin names to Spanish (and other languages)

The Claude desktop app's UI chrome is already localized (e.g., "Habilidades", "Conectores", "Complementos personales" appear in Spanish when the system language is set to Spanish). However, the built-in plugin display names (Marketing, Sales, Brand voice, Operations, Design, Productivity, Pdf viewer, Engineering, Finance, Product management, Zoom plugin) remain in English regardless of system language.

The app already has an es-419.json i18n file with translations for several of these terms (Sales → Ventas, Operations → Operaciones, etc.), but they aren't applied to plugin names since those come from remote plugin metadata rather than the i18n system.

Request: Apply localization to plugin display names, either by:

1. Including translated display names in the plugin metadata per locale, or
2. Using the existing i18n keys that already have these translations

Missing translations entirely: Brand voice, Pdf viewer, Zoom plugin.

Already in es-419.json but not applied:
