577-597: Avoid hard dependency on cURL extension

Calling curl_init() fatals on hosts where the cURL extension is missing. The plugin never required cURL before, so this new method can white-screen sites. Use the WP HTTP API (it gracefully falls back to available transports) or at least guard for cURL availability, keeping redirects disabled so you can still detect the 302.

-	$curl = curl_init();
-
-	curl_setopt_array(
-		$curl,
-		array(
-			CURLOPT_URL           => $file_url,
-			CURLOPT_NOBODY        => true,
-			CURLOPT_CUSTOMREQUEST => 'GET',
-		)
-	);
-
-	curl_exec( $curl );
-	$httpcode = curl_getinfo( $curl, CURLINFO_HTTP_CODE );
-	curl_close( $curl );
-
-	if ( 302 === $httpcode ) {
-		return true;
-	}
-
-	return false;
+	$response = wp_remote_head(
+		$file_url,
+		array(
+			'redirection' => 0,
+			'timeout'     => 5,
+		)
+	);
+
+	if ( is_wp_error( $response ) ) {
+		return false;
+	}
+
+	$status_code = wp_remote_retrieve_response_code( $response );
+
+	return 302 === $status_code;
