QR-Kompression: pako.deflateRaw + SDP-Dictionary statt base45

- base45/CompressionStream entfernt, durch pako.deflateRaw + base64 ersetzt
- SDP-Dictionary aus 10 echten SDP-JSONs (Chrome+Firefox) → 97.5% Kompression
- Korrupte pako.min.js durch CDN-Version ersetzt
- Tote Altlasten entfernt: hexToBuf, _fullSDPData/getFullSDPData, CRYPTO-UPDATE.md
- Debug-Panel: QR-Click kopiert base64, Raw-Data-Click kopiert JSON
- test-pairing.html an neue pack/unpack-API angepasst

-KONTEXT
-Vanilla-ECMAScript-Projekt. Mein aktuelles Protokoll committet Geheimnisse
-per H(secret) und teilt einen Schlüssel n-of-n auf. Ich ersetze das durch ein
-2-von-3 Threshold-Schema: Pedersen-DKG + Threshold-ElGamal mit verifizierbarer
-verteilter Entschlüsselung (Chaum-Pedersen-Beweise statt blankem Hash).
-Die fertige npm-Library threshold-elgamal scheidet aus: sie funktioniert
-zuverlässig nur mit threshold == Teilnehmerzahl, nicht mit 2-von-3.
-
-AUFGABE
-1. Inspiziere zuerst das Repo: finde den bestehenden Commit-/Keypart-Code,
-   bestimme die öffentliche Schnittstelle (welche Funktionen rufen Aufrufer
-   auf), und liste sie mir auf, BEVOR du etwas änderst.
-
-2. Füge @noble/curves als Fundament hinzu (auditiert, dependency-frei).
-   Verifiziere die aktuelle Version aus dem npm-Registry, bevor du pinst.
-   KEINE selbstgebaute Feldarithmetik, KEIN eigenes BigInt-Modular-Inverse –
-   alles über noble.
-
-3. Implementiere mit threshold=2, parties=3 auf einer Prime-Order-Gruppe
-   (Ristretto255 via @noble/curves bevorzugt):
-   - Pedersen-VSS / Pedersen-DKG: zwei Polynome Grad 1, Koeffizienten-
-     Commitments C_k = g^a_k · h^b_k, h mit unbekanntem log_g(h).
-   - Verteilte Schlüsselerzeugung: jede Partei dealt einen Beitrag, jede
-     verifiziert jeden empfangenen Share gegen die Commitments.
-   - Threshold-ElGamal als KEM: Payload NICHT direkt mit ElGamal. Rekonstruiere
-     per 2 partiellen Entschlüsselungen das gemeinsame Gruppenelement, leite
-     daraus per HKDF-SHA256 einen 256-bit Key ab, verschlüssele das Payload mit
-     AES-256-GCM (WebCrypto subtle, nicht selbst gebaut).
-   - Jede partielle Entschlüsselung trägt einen Chaum-Pedersen-Beweis der
-     DL-Gleichheit; verifiziere VOR der Lagrange-Kombination.
-
-4. Behalte die bestehende öffentliche Schnittstelle bei (gleiche Signaturen),
-   damit Aufrufer unverändert bleiben. Markiere den alten Code deprecated statt
-   ihn zu löschen.
-
-5. Tests: (a) 2 von 3 entschlüsseln erfolgreich, (b) 1 allein scheitert,
-   (c) manipulierte partielle Entschlüsselung wird durch die Verifikation
-   abgelehnt, (d) manipulierter VSS-Share fliegt bei der DKG-Verifikation auf,
-   (e) echtes Payload Round-Trip.
-
-EINSCHRÄNKUNGEN / WARNUNG
-- Das ist selbstgebaute Threshold-Krypto. Setze einen unübersehbaren Kommentar
-  an den Kern: nicht auditiert, Komposition über noble ist ungeprüft.
-- Nutze ausschließlich noble + WebCrypto für alle Primitiven. Erfinde keine
-  Kurven-, Hash- oder Symmetrie-Operationen selbst.
-- Konstante-Zeit-Verhalten kannst du in reinem JS nicht garantieren – halte das
-  im Kommentar fest.
-- Ändere nichts an meiner Geheimnis-/Key-Persistenz, ohne vorher zu fragen.
