feat: add AnonymityGuard, opt-in-by-default DHT sharing proof suite, and canonical chart pipeline docs

| """benchmarks/proof_anonymous_opt_in_sharing.py | |
| Live 12-Node UDP BEP-44 Proof Suite for Armiger Anonymous & Opt-In-By-Default DHT Sharing. | |
| Executes three machine-verifiable proofs over real 127.0.0.1 UDP Kademlia sockets: | |
| - Proof 1 (Opt-In Default Zero-Egress Proof): | |
| Instantiates ArmigerUltraPipeline, ArmigerPipeline, ArmigerDHTRSIEngine, ArmigerDHTDBSync, | |
| SeriesWebhookAdapter, MovieWebhookAdapter, and the 3 integration bridges (DH-Waypoint, | |
| Bitmagnet, Arr Webhook Receiver) with default arguments; feeds 100 synthetic webhook and | |
| catalog events; proves opt_in_sharing is False everywhere and 0 outbound DHT bundles / | |
| 0 UDP put packets are emitted. | |
| - Proof 2 (Wire-Level Canary & PII Firewall Proof): | |
| Injects 500 adversarial canary mutations across 10 categories (home/LAN IPs, Tailscale/IPv6, | |
| macOS/Linux paths, raw release titles, magnet/tracker URLs, 40-char infohashes, passkeys/API | |
| keys, .local/.lan/.internal/FQDN hostnames, high-precision timestamps/external IDs, and | |
| single-item unaggregated updates n < min_k_samples / unexpected schema keys) into an opted-in | |
| 12-node UDP BEP-44 swarm. Proves 100% (500/500) are blocked or stripped before wire | |
| transmission and 0% (0/500) of canary substrings ever appear in any raw UDP packet on the wire. | |
| - Proof 3 (Unlinkability & DP Convergence Proof): | |
| Across a 12-node opted-in UDP BEP-44 swarm over 5 epochs, proves ephemeral Ed25519 key | |
| rotation unlinkability (60/60 unique keys, random-guess linkability 1/12 = 8.33%), coarse UTC | |
| hour timestamp bucketing (100% ts % 3600 == 0), single-sample membership inference defense, | |
| and swarm calibration ECE + Armiger-Ultra F1 convergence. | |
