 * Verifies the GitHub webhook signature using HMAC-SHA256.

 * GitHub sends a signature in the `X-Hub-Signature-256` header in the format:
 * `sha256=<HMAC hex digest>`
 *
 * This function computes the expected signature using the stored webhook secret
 * and compares it with the provided signature using a constant-time comparison.
 *
 * @returns true if signature is valid or no secret is configured, false otherwise
