static PreparedNonceWithProof	from_parts (PreparedNonce prepared, NonceProof proof)
	Bundles a prepared nonce with its matching public nonce proof.

Detailed Description

The proof is always present and the secret nonce scalar remains non-serializable. This avoids forcing callers to branch on a maybe-present proof after the type has already crossed an API boundary.
