feat(ttp): E.3.8 R0049-R0053 canary fingerprint cohort

5 YAMLs for the canary-fingerprint cohort per Appendix B / A.9:
navigator.webdriver flag, automation canvas/audio/WebGL hash match,
WebRTC IP leak, TZ/lang vs geo mismatch, platform inconsistency.
CanaryFingerprintLifter (E.3.11) consumes by rule_id.

test_canary_rules.py: YAML-present + inert-in-v0 + xfail(strict)
gated on E.3.11.
