auto-claude: subtask-2-2 - Add INFO-SUPPRESSED section to report output

- Added lineForSuppressedFinding() to format suppressed findings
- Added INFO-SUPPRESSED section showing suppressed findings with reason and date
- Suppressed findings are not counted in summary (already filtered)
- Follows existing code patterns for report sections
