Function mockVerify

mockVerify(
    _publicKey: string,
    message: string | Uint8Array<ArrayBufferLike>,
    signature: string,
    privateKey: string,
): boolean
Verify a mock signature produced by mockSign.

Re-signs the message with the private key and checks that the result matches the provided signature.
Parameters
- _publicKey: string
  Hex-encoded public key (unused; included for API parity).
- message: string | Uint8Array<ArrayBufferLike>
  UTF-8 string or bytes that were signed.
- signature: string
  Hex-encoded signature from mockSign.
- privateKey: string
  Hex-encoded private key used to produce the signature.
Returns boolean
true if the signature matches, false otherwise.
Example
```
import { mockSign, mockVerify, TEST_KEYS } from "@sebastienrousseau/crypto-testing";

const sig = mockSign(TEST_KEYS.ed25519.privateKey, "msg");
const ok = mockVerify(TEST_KEYS.ed25519.publicKey, "msg", sig, TEST_KEYS.ed25519.privateKey);
```
