"""DRIFT Bug Bot — the beast.

Orchestrates recon, findings tracking, report generation, and
Bugcrowd submission for bug bounty hunting.

Safe by design:
- Rate-limited API calls (1 req/sec default)
- Scanner rate limits (nuclei -rl 10, ffuf -rate 10)
- Scope enforcement before any active recon
- No destructive actions
