Add E2E tests, bump cloudcheck to 11.x

[liquidsec]

Summary

• Adds end-to-end tests that install bbot into a fresh temp venv and run real CLI scans
• Bumps cloudcheck dep to >=11.0.0,<12 (fixes undeclared httpx runtime dep in cloudcheck 10.x)

E2E Tests

• test_install_and_help - installs bbot from local source, verifies bbot -h works
• test_scan_dns - DNS-only scan against one.one.one.one, asserts DNS_NAME events with resolved IPs and output files
• test_scan_web - spins up a local HTTP server, runs a spider scan, asserts excavate discovers links across pages
• test_clean_shutdown - verifies scan reaches FINISHED status, no [CRIT] errors, no orphaned bbot processes
