Add i18n support for homepage (国际化官网首页)

[Copilot]

The homepage was hardcoded in English. This adds Chinese translations while leveraging the existing middleware and routing infrastructure.

Changes

Created apps/docs/lib/homepage-i18n.ts

• TypeScript interface HomepageTranslations defining all translatable strings
• English and Chinese translation objects
• getHomepageTranslations(lang) selector with fallback to English

Updated apps/docs/app/[lang]/page.tsx

• Changed to async function to extract lang from route params
• Replaced hardcoded strings with translation variables
• All sections now localized: hero, features, personas

Example

// Before
<h1>The ObjectStack Protocol</h1>

// After
const t = getHomepageTranslations(lang);
<h1>{t.hero.title.line1} <br/> {t.hero.title.line2}</h1>

Pull request overview

This PR adds internationalization (i18n) support to the ObjectStack homepage, enabling both English and Chinese language versions. The implementation leverages the existing Next.js i18n routing infrastructure while keeping translations maintainable through a centralized module.

Changes:

• Created a new i18n module with TypeScript-typed translations for English and Chinese
• Converted the homepage component to async to access route parameters for language detection
• Replaced all hardcoded English strings with dynamic translation variables

File	Description
apps/docs/lib/homepage-i18n.ts	New translation module defining the HomepageTranslations interface and providing English/Chinese translation objects with a language selector function
apps/docs/app/[lang]/page.tsx	Updated homepage to extract language from route params and use translations instead of hardcoded strings
packages/spec/src/system/manifest.test.ts	Removed unused MenuItem test cases and import
packages/spec/src/data/field.test.ts	Fixed extraneous closing brace

[Copilot]

The removed MenuItemSchema tests provided validation coverage for the menu item structure. Ensure that menu item validation is adequately covered elsewhere in the test suite, or consider keeping these tests to maintain comprehensive schema validation.
