/**
 * Ephemeral session key generation.
 * Future extension: delegation chain Root -> Agent -> Session.
 * Not implemented in beta — this file is a placeholder.
 *
 * Future design (spec section 4.2):
 *   Root Key signs delegation VC from Agent DID to Session DID
 *   Session Key signs VP (KB-JWT)
 *   Gateway verifies VC chain (original VC + delegation VC)
