feat(i18n): add Spanish (es) locale for desktop UI

[valeracjva]

Summary

Adds complete Spanish (es) locale support for the Hermes Desktop app, using defineLocale() for a partial locale that falls back to English for any untranslated keys (same pattern as ja.ts).

Changes

File	Change
apps/desktop/src/i18n/es.ts	New — 2,055 lines of Spanish translations covering all major UI sections
apps/desktop/src/i18n/catalog.ts	Register es in TRANSLATIONS
apps/desktop/src/i18n/languages.ts	Add es entry + 8 locale aliases
apps/desktop/src/i18n/types.ts	Add 'es' to Locale type

Coverage

Translated sections include: common, fileMenu, boot, notifications, remoteDisplayBanner, titlebar, keybinds, language, settings (full), skills hub, starmap, agents, commandCenter, messaging, profiles, cron, artifacts, sidebar, composer, statusStack, updates, install, onboarding, modelPicker, shell, rightSidebar.

Testing

• Untranslated keys gracefully fall back to English via defineLocale().
• Locale aliases cover es, es-es, es-ar, es-mx, es-419 for broad regional support.
• No unused imports; follows existing ja.ts partial locale pattern.

Closes #68822

Duplicate of #41230: both implement the same Desktop Spanish locale catalog and registration surface. #54415 remains related because it also includes dashboard translation work.

Thanks for the Spanish Desktop locale contribution. The underlying need remains real: current main has no apps/desktop/src/i18n/es.ts or Spanish locale registration.

Problems

• This branch is based on a88512b114059fff642d60d54cbf30d5793c6c37 and is currently DIRTY. Current locale registration has since changed for Arabic in apps/desktop/src/i18n/catalog.ts:1-13, apps/desktop/src/i18n/languages.ts:32-37, and apps/desktop/src/i18n/types.ts:8 (commit 5b6990e7a0).
• The diff changes no tests, despite adding Spanish aliases. Existing alias, exact-ID, and persistence expectations are covered in apps/desktop/src/i18n/languages.test.ts:6-46.

Suggested changes

• Preserve any distinct Spanish copy or aliases by salvaging them into the current feat(desktop): add Spanish locale #41230 catalog and its current test coverage rather than applying this stale registration patch wholesale.
• Add alias-normalization and config-selection coverage for es following the existing i18n tests.

Automated hermes-sweeper review.

Cerrando en favor de #41230 que tiene implementación más completa con tests, fix del placeholder y mayor cobertura de secciones. Gracias por la revisión.
