feat: Expand preset library — cybersecurity, climate, Korea, healthcare presets with sample GeoJSON data

[alohays]

Problem

monitor-forge currently offers only 7 presets across 3 domains (technology, finance, geopolitics). This causes several issues:

1. Limited domain coverage: worldmonitor covers 5+ domains (geopolitics, tech, finance, commodity, positive news) while monitor-forge only has 3. High-demand domains like cybersecurity, climate/environment, Korea news, and healthcare are missing
2. All map layers are empty: Every preset has layers: []. Despite the map being a core feature, applying a preset shows nothing but an empty map
3. No sample GeoJSON data: The data/geo/ directory only has a single test file. Without real usable data per preset, users can't experience the value of map layers
4. Minimal map configuration: Most presets don't enable advanced features like dayNightOverlay, atmosphericGlow, or idleRotation

As a result, applying a preset only produces "RSS news feed + empty map", making it hard for users to appreciate monitor-forge's full potential.

Solution

Phase 1: Add new domain presets (4 domains, 8 presets)

Preset	Domain	Sources	Panels	Description
cyber-minimal	cybersecurity	3	2	Krebs on Security, Bleeping Computer, CISA Alerts
cyber-full	cybersecurity	7+	4	+ CVE DB, VirusTotal Blog, Threat Intelligence RSS, Dark Reading
climate-minimal	climate	3	2	NASA Climate, Carbon Brief, NOAA
climate-full	climate	6+	4	+ Natural disaster data, IPCC, Climate Home News
korea-minimal	korea	3	2	Yonhap News, Hankyoreh, Chosun Ilbo
korea-full	korea	7+	4	+ Bank of Korea, Korean tech news, KOSPI-related
health-minimal	healthcare	3	2	WHO, CDC, NIH
health-full	healthcare	6+	4	+ PubMed, The Lancet, ProMED

Phase 2: Add map layers and GeoJSON to existing presets

Add meaningful layers and sample data to existing -full presets:

• tech-full: data/geo/tech-hubs.geojson (global tech hub points layer)
• finance-full: data/geo/financial-centers.geojson (global financial centers)
• geopolitics-full: data/geo/conflict-zones.geojson (conflict zone points)
• cyber-full: data/geo/threat-origins.geojson (cyber threat origin points)
• climate-full: data/geo/natural-disasters.geojson (recent natural disaster locations)

Phase 3: Enhance preset metadata

Add a _meta field to preset JSON for richer display in the wizard and preset list:

{
  "_meta": {
    "category": "cybersecurity",
    "difficulty": "beginner",
    "requires_api_keys": ["GROQ_API_KEY"],
    "optional_api_keys": ["OPENROUTER_API_KEY"],
    "preview_description": "Real-time cyber threat intelligence dashboard"
  }
}

Implementation Details

1. Create preset files: Add 8 JSON files to presets/ directory

   • Each preset uses only working, publicly accessible RSS/API URLs
   • korea-* presets set language: "ko" for Korean-language sources

2. GeoJSON data files: Add domain-specific sample data to data/geo/

   • Each file contains 10-30 lightweight Features
   • Follow FeatureCollection + properties pattern

3. Update existing presets: Add GeoJSON-referencing layers to tech-full.json, finance-full.json, geopolitics-full.json

   • Use data.source: 'static', data.path: 'data/geo/<file>.geojson' pattern

4. Improve preset list command: Update forge/src/commands/preset.ts to display _meta info (category, difficulty, required keys)

Acceptance Criteria

• 8 new preset files are added to presets/
• All RSS URLs in each preset are working, publicly accessible feeds
• At least 5 domain-specific GeoJSON files are added to data/geo/
• The 3 existing *-full presets each have at least 1 map layer added
• All presets pass MonitorForgeConfigSchema.parse() validation
• forge preset list displays 15 presets (existing 7 + new 8)
• forge preset apply <name> → forge validate passes without errors for all new presets
• GeoJSON files referenced by layers pass forge validate static file existence checks

Priority Rationale

Presets define the "out-of-the-box" experience. Even if Issue #28's onboarding wizard guides users perfectly, a weak preset selection means a weak first impression. Empty map layers fail to showcase the map feature's value. The korea-* presets directly serve the project's target user base, while cyber-* and climate-* cover globally high-interest domains.
