Phase 2: Scan engine, agents, reports, and end-to-end pipeline

- AI Planner (NVIDIA-based dynamic planning) + RulePlanner fallback
- Workflow engine with ScanOrchestrator and progress tracking
- Recon agents: DNS record discovery + Technology fingerprinting
- Web agents: Crawler (23 paths), XSS scanner, SQLi scanner
- API agent: Endpoint discovery (20+ patterns)
- Secrets agent: Pattern-based + entropy-based secret detection
- Verification agent: Finding audit pass
- Markdown report generator with executive summary, findings table,
  risk matrix, and asset inventory
- Rich progress bars with real-time scan UI
- End-to-end pipeline: target → plan → execute → report
