fix: table coverage only counts functional sections + specific missing row feedback - Closes #21

- _quick_validate: table rows only from functional sections
- Track specific missing rows with content for targeted feedback
- _build_coverage_feedback: includes missing row details
- Denominator: 24->18 rows, coverage: 54%->67%
