feat(skill): add e-commerce, business data, weather/maps, travel to description (#68)

## Summary
- Expand the `skills/agentkey/SKILL.md` frontmatter `description`
trigger list with four new data categories: e-commerce product data,
business/company data, weather & maps/geolocation, and travel
(flights/hotels)
- Helps agents route these query types to AgentKey instead of built-in
WebSearch/WebFetch

## Notes
- Description length is 613 characters, well within the 1024-character
Agent Skills spec limit
- No behavior change beyond skill triggering scope
