docs: Add comprehensive digest for test coverage assessment system

Documents the complete implementation and critical bug fix of the test
coverage assessment system including:

- Sophisticated requirement extraction using regex patterns
- Priority-based categorization and keyword matching system
- Integration with TDD workflow via make test-coverage command
- Critical false positive bug fix (33.3% -> 0.0% for untested issues)
- Technical architecture and validation results

This system significantly enhances our TDD workflow by providing
quantitative measurement and actionable recommendations for test
completeness while preventing dangerous false confidence in coverage.
