[FEATURE]: add i18n support for desktop application menu (zh-CN)

[2024sy]

Feature hasn`t been suggested before.

• I have verified this feature Im about to request hasnt been suggested before.

Describe the enhancement you want to request

The OpenCode desktop application menu bar (File/Edit/View/Go/Window/Help) currently has no i18n support - menu labels are hardcoded in English in packages/app/src/desktop-menu.ts, even when the app language is set to Chinese (zh-CN).

Id like to add Chinese translations for all desktop menu items by integrating them into the existing i18n framework. The windows-app-menu.tsxcomponent already runs in the renderer process whereuseLanguage()is available, so this is a straightforward addition ofmenu.*` i18n keys.

Related closed issues:

• Windows desktop app menu (File/Edit/View/Go) not translated when using French locale #34104 (French locale - same root cause)
• Some parts of the desktop have not been localised into Chinese #30884 (Chinese locale - same root cause)

Implementation approach:

• Add 48 menu.* i18n keys to en.ts and zh.ts
• Update desktop-menu.ts labels to use i18n keys
• Wire useLanguage() translation in windows-app-menu.tsx
• Resolve labels in menu.ts for macOS via en.ts import

This issue might be a duplicate of existing issues. Please check:

• Windows desktop app menu (File/Edit/View/Go) not translated when using French locale #34104: Windows desktop app menu not translated — describes the exact same untranslated desktop menu problem, identifies the same root-cause files (desktop-menu.ts, windows-app-menu.tsx), and was recently closed.
• Some parts of the desktop have not been localised into Chinese #30884: Some parts of the desktop have not been localised into Chinese — same area (Chinese localisation of the desktop app).

If you believe this was flagged incorrectly, please let a maintainer know.
