feat: Nightly news generation script and GitHub Actions workflow

[Copilot]

Automates daily article generation from Swedish Riksdag/Government data: queries MCP for documents published in the last 24 hours, applies a ≥5 document threshold per type to suppress empty articles on low-activity days, generates all 14 language versions, and refreshes indexes/sitemap.

New: scripts/generate-daily-news.js

Four-stage pipeline reusing existing generate-news-enhanced.js generators:

Stage	Description
Discovery	search_dokument with 24h lookback for prop, mot, bet
Threshold	Skip types with < N new docs (default 5, --force to override)
Generation	Delegates to existing per-type generators → 14 languages
Post-process	Runs index + sitemap scripts as child processes

# Manual dry-run to see what would generate
node scripts/generate-daily-news.js --dry-run --lookback-hours=48 --threshold=3

# Full run, all languages
npm run generate-daily-news -- --languages=all

Key behaviours:

• Exits 0 even on MCP unavailability (cold starts, outages) — scheduled workflow stays green on quiet days
• Week-ahead article always queued regardless of threshold
• Writes news/metadata/daily-generation-status.json for downstream workflow inspection

New: .github/workflows/nightly-news-generation.yml

• Cron: 0 1 * * * (01:00 UTC = 02:00 CET winter / 03:00 CEST summer)
• workflow_dispatch exposes all pipeline knobs: languages, threshold, lookback_hours, force_generate, dry_run
• Creates PR via peter-evans/create-pull-request only when articles are actually written
• SHA-pinned actions, step-security/harden-runner with egress audit, least-privilege permissions (contents: write, pull-requests: write)
• Uploads generation artifacts (30-day retention), writes step summary with document counts

<issue_title>Document Article Enhancement Workflow and MCP Integration Patterns</issue_title>
<issue_description># 📋 Issue Type
Documentation / Knowledge Management

🎯 Objective

Create comprehensive documentation of the article enhancement workflow, MCP integration patterns, and content generation best practices based on the successful completion of Issues #306-334.

📊 Current State

Gap: While enhancement was successful, there's no consolidated documentation for:

• Step-by-step workflow for enhancing news articles
• MCP tool usage patterns and examples
• Content quality standards and templates
• Translation workflow for 14 languages
• Common pitfalls and solutions

Scattered Information: Knowledge exists across:

• Closed PRs Resolve merge conflicts preserving comprehensive content and professional translations #307, Address PR review comments: fix translation script logic and HTML validation issues #312, Fix translations for 2026-02-18 committee reports; document remaining work #313, Fix mixed-language metadata and add safety guards for translation scripts #314, Add 42 news articles for 2026-02-19 #326, Fix placeholder content, payloadPath security, schema mismatch, and session init robustness #333, [WIP] Address review comments and update opposition motions articles #334
• Python scripts in scripts/
• Repository memories
• Issue descriptions Enhance Committee Reports Articles with Full Data Analysis and Commentary (2026-02-10 to 2026-02-14) #306-311

🚀 Desired State

Create ARTICLE_ENHANCEMENT_GUIDE.md with:

• 📋 Workflow Overview: Step-by-step process
• 🔧 MCP Integration: Tool examples and patterns
• ✍️ Content Standards: Quality checklist, word counts, structure
• 🌐 Translation Workflow: 14-language process
• 🎯 Quality Assurance: Validation steps
• 💡 Best Practices: Lessons learned
• ⚠️ Common Pitfalls: Issues and solutions

🔧 Documentation Structure

1. Workflow Overview

## Article Enhancement Workflow

### Phase 1: Data Collection (MCP)
1. Identify document IDs from article HTML
2. Fetch full details via riksdag-regering-get_dokument
3. Get supplementary data (committee, author, voting)
4. Validate data completeness

### Phase 2: Content Generation
1. Analyze document content and political context
2. Generate 150-400 word analysis per document
3. Create cross-cutting thematic analysis
4. Write "What to Watch" forward-looking section
5. Generate content-based title and description

### Phase 3: Multi-Language Translation
1. Start with Swedish (source language)
2. Translate to English for global audience
3. Translate to all 14 languages using guides
4. Validate RTL layouts (Arabic, Hebrew)

### Phase 4: Quality Validation
1. HTML validation (HTMLHint)
2. Link checking (all document URLs)
3. Accessibility (WCAG 2.1 AA)
4. SEO validation (unique titles, meta tags)

2. MCP Integration Patterns

## Riksdag-Regering MCP Tools

### Tool: get_dokument
**Purpose**: Fetch full document details
**Example**:
```javascript
riksdag-regering-get_dokument({
  dok_id: "HD01SkU19",
  include_full_text: true
})

Returns: title, summary, proposer, status, committee, full text
Use when: Need complete document information for analysis

Tool: get_utskott

Purpose: Get committee information
Example:

riksdag-regering-get_utskott()

Returns: All committee names, abbreviations, jurisdictions
Use when: Need full committee names and context

[Document all 32 MCP tools with examples]

### 3. Content Quality Standards
- Document analysis: 150-400 words
- Political context: Party positions, coalition dynamics
- Stakeholder impact: Who's affected, how
- Timeline: Chamber debate dates, voting schedule
- Title: 50-60 characters, content-specific
- Description: 150-160 characters, policy areas mentioned

### 4. Translation Best Practices
- Use translation guides for consistency
- Nordic languages first (SV, DA, NO) - similar to source
- RTL support for Arabic and Hebrew
- Validate character limits per language
- Complete UI localization (navigation, buttons)
