feat: expand SEO keyword localization to cover 50+ topic-specific terms across all 13 non-English languages

[Copilot]

The keyword localization batch script only covered ~31 basic template keywords, leaving ~50 topic-specific terms (artificial intelligence, weapons law, coalition government, social welfare, weekend analysis, etc.) in English across all non-English article pages — both in <meta name="keywords"> and JSON-LD "keywords" arrays.

Translation map expansion

• Added 50 new entries to SEO_KEYWORD_TRANSLATIONS in both scripts/fix-keywords-localization.ts and scripts/data-transformers/metadata.ts (synced for future article generation)
• Categories: political terms, security/defence, social/labour policy, economic, AI/technology
• Shared-form words (e.g. reform, interpellation, surveillance in French) intentionally map to the same surface form — not bugs

JSON-LD array format support

The replaceKeywords() function only matched the string format "keywords": "...". Added support for the array format used by newer articles:

// Before: only handled
"keywords": "committee reports, ..."

// Now also handles
"keywords": ["Committee Reports", "Ukraine Aid", "Data Protection"]
//            → ["委員会報告書", "Ukraine Aid", "データ保護"]  (ja)
//            → ["تقارير اللجان", "Ukraine Aid", "حماية البيانات"]  (ar)

Proper nouns (Ukraine Aid, Riksdag, NATO, Finance Committee) are correctly preserved in English via the existing fallback.

Bug fix

Hebrew translation for legislative session contained mixed Hebrew/CJK characters (מושב立法); corrected to מושב חקיקה. The one affected published article was patched directly.

Article updates

~458 articles updated across all 13 non-English languages.

<issue_description>## 📋 Issue Type
Bug Fix / Enhancement - SEO and Multi-Language Metadata

🎯 Objective

Translate the <meta name="keywords"> content in all non-English news articles from English to the target language, improving SEO discoverability for international audiences.

📊 Current State

All non-English news articles (~1,000+ files) have English-only keywords in their metadata:

Example (all languages show the same English keywords)

<!-- Danish article (news/2026-02-14-government-propositions-da.html) -->
<meta name="keywords" content="government, propositions, parliament, legislation, Swedish Parliament, Riksdag, politics, Sweden">

<!-- Japanese article (news/2026-02-14-government-propositions-ja.html) -->
<meta name="keywords" content="government, propositions, parliament, legislation, Swedish Parliament, Riksdag, politics, Sweden">

<!-- Korean article (news/2026-02-14-government-propositions-ko.html) -->
<meta name="keywords" content="government, propositions, parliament, legislation, Swedish Parliament, Riksdag, politics, Sweden">

Impact

• SEO: Non-English search engines cannot match articles to queries in the user's language
• Discoverability: Japanese/Korean/Chinese/Arabic users searching in their language won't find these articles
• Professionalism: English metadata on non-English pages signals incomplete localization

🚀 Desired State

Each article's keywords match its language:

<!-- Danish -->
<meta name="keywords" content="regering, lovforslag, parlament, lovgivning, Sveriges Riksdag, politik, Sverige">

<!-- Japanese -->
<meta name="keywords" content="政府, 法案, 議会, 立法, スウェーデン国会, 政治, スウェーデン">

<!-- Korean -->
<meta name="keywords" content="정부, 법안, 의회, 입법, 스웨덴 의회, 정치, 스웨덴">

<!-- Arabic -->
<meta name="keywords" content="حكومة, مقترحات, برلمان, تشريع, البرلمان السويدي, سياسة, السويد">

🔧 Implementation Approach

Step 1: Create Keyword Translation Map

Add a keyword translation map to the article generation system (or as a standalone dictionary):

const KEYWORD_TRANSLATIONS: Record<Language, Record<string, string>> = {
  da: { 'government': 'regering', 'propositions': 'lovforslag', 'parliament': 'parlament', 'legislation': 'lovgivning', 'Swedish Parliament': 'Sveriges Riksdag', 'Riksdag': 'Riksdag', 'politics': 'politik', 'Sweden': 'Sverige', 'committee': 'udvalg', 'reports': 'betænkninger', 'opposition': 'opposition', 'motions': 'forslag' },
  // ... for all 12 non-EN languages
};

Step 2: Create Batch Fix Script

Create a script that:

1. Scans all news/*-{lang}.html files where lang ≠ 'en'
2. Extracts <meta name="keywords" content="...">
3. Translates each keyword to the target language
4. Rewrites the meta tag
5. Also updates "keywords" in JSON-LD structured data if present

Step 3: Update Article Template

Update scripts/article-template/template.ts to use localized keywords during generation, preventing this issue for future articles.

Step 4: Validate

• Verify all meta keywords are in the target language
• Ensure JSON-LD keywords match
• HTML validation passes
