feat: implement centralized taxonomy for programmatic SEO
- Create taxonomy system with oils.json (5 oils) and concerns.json (9 concerns) - Migrate 10 content files to new data/content/oil-for-concern/ structure - Add scripts: generate-urls.js, validate-taxonomy.js, migrate-content.js - Update dataLoader.ts to use centralized taxonomy - Generate 40 URLs (10 pairs × 4 languages) - Create sitemap-programmatic.xml for SEO - Update by-oil and by-concern directory pages
