+ * Security Validation Module for MSDO Issue Assistant
+ * 
+ * SECURITY DESIGN:
+ * - Core detection logic is in code (open source)
+ * - Specific patterns can be overridden via GitHub Secrets (hidden)
+ * - This prevents attackers from seeing exact patterns to bypass
+ * 
+ * Pattern sources (in priority order):
+ * 1. GitHub Secrets (if provided) - hidden from attackers
+ * 2. Built-in patterns (visible in code) - baseline protection
