fingerprint_scan_test.py

"""Test against fingerprint-scan.com and CreepJS.

Tests the specific headless detection signals flagged by the community:
- noTaskbar, noContentIndex, noContactsManager, noDownlinkMax
- Bot risk score (fingerprint-scan.com)
- Headless/stealth percentages (CreepJS)
- Full CreepJS signal breakdown (likeHeadless, headless, stealth)

Usage:
