Adds the load-bearing primitives for obfuscated browser-fingerprinting canaries. Step 3 (HTML/SVG generators) and step 4 (worker-side fingerprint ingestion) build on top of these. * decnet/canary/obfuscator.py - javascript-obfuscator wrapper. Seed and polymorphic config bits both derive from the callback token, so output is byte-identical for the same mint (preserving the generator determinism contract from base.py) and structurally distinct across mints. * decnet/canary/fingerprint_payload.js - port of canary-self-test.html with the rendering UI stripped. Two placeholders (BEACON_URL, MINT_UUID) substituted before obfuscation. MVP beacon strategy: bare-open GET pixel first, then base64url-encoded fingerprint as query params on subsequent GETs (chunked above ~6KB) so the existing worker records hits before step-4 lands. * decnet/canary/_obfuscate_helper.js - Node subprocess helper that reads code+options JSON from stdin and writes obfuscated JS to stdout. Vendored javascript-obfuscator under decnet/canary/. * tests/canary/test_obfuscator.py - determinism, per-mint divergence, template substitution, Node syntax check, error path.
