## Feature Description
In addition to Open Graph meta tags, generate JSON-LD structured data (`<script type="application/ld+json">`) for improved SEO and rich search results.

## Problem or Use Case
Open Graph is for social sharing, but Google and other search engines primarily use JSON-LD structured data for rich results (breadcrumbs, article info, FAQ, product reviews, etc.). A comprehensive SEO extension should provide both.

## Proposed Solution
Add optional JSON-LD output alongside OG tags:
1. **Article** schema — `@type: Article` with headline, datePublished, author, image
2. **WebPage** schema — For non-article pages
3. **BreadcrumbList** schema — Based on Joomla menu hierarchy
4. **Organization** schema — Site-wide, configured in plugin settings
5. **Product** schema — When VirtueMart/HikaShop adapter is active

## Implementation Details
- New `JsonLdBuilder` helper class in `plg_system_mokoog`
- Output in `onBeforeCompileHead` alongside OG tags
- Plugin configuration toggle: Enable/disable JSON-LD per schema type
- Validate output against Google's Structured Data Testing Tool format
