Add scan_timestamp column to scan_results. save_scan_results now inserts with a timestamp and prunes versions beyond max_versions (default 5). get_scan_results returns only the latest version by default, with optional scan_timestamp parameter for loading specific versions. New get_scan_versions method returns available versions for a (file, profile, model) tuple. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
