refactor(schema): reduce generate_article_schema complexity from 55 to 7

- Extract author info into _extract_author_info helper method
- Extract date handling into _extract_dates with _normalize_iso_date helper
- Extract image handling into _extract_images helper method
- Extract tags/keywords into _extract_keywords helper method
- Extract engagement metrics into _extract_engagement_metrics helper
- Extract content metrics into _extract_content_metrics helper
- Refactor main method as orchestrator calling helper methods
- Remove duplicate username extraction code blocks
- Update COMPLEXITY_REFACTORING.md to mark task as completed

 - Create a mapping/strategy pattern for content type detection
 - Reduce nested conditionals using early returns
 
-**Implementation:**
+=======
 
-- Created `CONTENT_TYPE_MATCHERS` class constant for configuration-driven matching
-- Extracted tag extraction logic into `_extract_tags()` helper method
-- Created `_matches_content_type()` helper method for matching logic
-- Simplified main method to iterate through matchers with early return
