Improve extraction scripts, validation, and documentation

Enhance article extraction and validation systems with better error handling, retry logic, and content cleaning.

Script improvements:
- Add retry logic with exponential backoff for API calls
- Implement 60-second timeout for Anthropic API requests
- Improve HTML cleaning with Substack-specific filters
- Remove navigation, footer, and UI noise from extracted content
- Better HTML entity decoding

Validation enhancements:
- Add duplicate URL detection across articles
- Validate topic assignments against known topics
- Enhanced error reporting with specific issue types

GitHub Actions:
- Add build output validation step
- Verify /out directory exists before PR creation
- Count generated HTML files for sanity check

Documentation updates:
- Update project stats (26 articles, ~30 pages)
- Document v1.2 improvements
- Add changelog entries

Type safety:
- Improve topics.ts type definitions
