• save_baseline — snapshot current findings as a JSON baseline
• scan_with_baseline — scan and report only new findings not in baseline
• Uses SHA-256 fingerprinting consistent with dedup tracking

CI Quality Gates (1 new MCP tool)

• check_quality_gate — pass/fail/warn verdicts based on severity thresholds
• Configurable fail_on, warn_on, max_findings thresholds
• Exit codes: 0 (pass), 1 (fail), 2 (error)

Bulk APIs (2 new MCP tools)

• scan_files — scan multiple files in a single call
• scan_diff — parse unified diffs (git diff), scan only added lines
