/**
 * ANAMNESIS T-OPRF Client — Threshold Oblivious Pseudo-Random Function
 *
 * Client-side password hashing, agent communication, and OPRF reconstruction.
 * Part of the 8th protocol primitive (K8 — Distributed Recognition).
 *
 * For full privacy (password never leaves device), the SDK must perform
 * EC point blinding using secp256k1. This requires @noble/secp256k1.
 * Install: npm install @noble/secp256k1
 *
 * Without @noble/secp256k1, the SDK sends the password hash directly
 * to agents (less private but functionally correct for testnet).
