GDPR Shift-Left MCP Server -- Adversarial & GDPR-Accuracy Judge Suite

These judges go beyond structural checks and exercise the MCP server with:
  - Injection / manipulation attacks (XSS, SQL injection, prompt injection)
  - GDPR legal accuracy validation against known regulatory text
  - Boundary / edge-case exercises for every tool path
  - Cross-reference verification (DSR articles, ROPA Art. 30 fields, DPIA Art. 35)
  - Diverse real-world prompts that exercise compliance logic end-to-end

All expected values are sourced from Regulation (EU) 2016/679 (GDPR).
