feat(ttp): E.3.11 CanaryFingerprintLifter (R0049-R0053)

Browser-payload derivations per Appendix A.9: navigator.webdriver flag,
canvas/audio/WebGL automation hash matches (Puppeteer/Playwright/
Selenium/curl-impersonate), WebRTC IP leak, TZ/language vs source-IP
geo mismatch, navigator.platform vs userAgent vs WebGL renderer
inconsistency.

Evidence shape pinned to CanaryFingerprintEvidence (metric +
matched_signature) — raw fingerprint blobs (canvas hashes, full UAs,
navigator.platform values) explicitly NOT carried into TTPTag.evidence
per TTP_TAGGING.md §'Hard parts §7' (enrichment vs tag boundary). The
identity-merge guard rail is preserved: composite fp.id matches across
IPs are NOT a TTP, so no rule fires on the bare hash.

Tests: tests/ttp/test_canary_fingerprint_lifter.py per-rule positive +
negative + evidence-shape guard + state modulation.
tests/ttp/rule_precision/test_canary_rules.py xfail flipped to real
precision (R0049/R0050/R0051/R0053 H-band ≥95%; R0052 M-band ≥80%).
