This startBlockingProcess() helper is identical to the one added in JsonRpcClientTest. Consider extracting it into a shared test utility to avoid duplication and keep the OS-specific command logic consistent across tests.

Copilot uses AI. Check for mistakes.

@Test
void connectToServerStdioMode() throws Exception {
var options = new CopilotClientOptions();
var manager = new CliServerManager(options);

// Create a dummy process for stdio mode
Process process = new ProcessBuilder("cat").start();
Process process = startBlockingProcess();
try {
JsonRpcClient client = manager.connectToServer(process, null, null);
assertNotNull(client);

The startBlockingProcess() helper is duplicated here and in CliServerManagerTest. Consider extracting it into a shared test utility (e.g., a package-private helper in src/test/java/com/github/copilot/sdk/) so future tweaks to the blocking command/OS detection only need to be made in one place.
