FIX: Add baseline system to prompt injection scanner for false positives
The prompt injection scanner was flagging too many false positives from: - Legitimate variable names (e.g., "prompt", "system") - Documentation with these words - Legitimate Unicode characters in prompt templates Changes: - Added baseline system (.prompt_injections.baseline) to track known findings - Scanner only flags NEW findings not in baseline - Updated GitHub Actions workflow to use baseline system - Added --baseline, --update-baseline, and --force-baseline options Usage: - Normal scan: Uses existing baseline, only NEW findings fail - Update baseline: --update-baseline to add legitimate findings - Force new baseline: --force-baseline to start fresh Co-Authored-By: Claude <noreply@anthropic.com>
