Use a controlled binary path in the probe fixture.

On Windows, codex can resolve to a .cmd or .bat shim. The spawner then receives empty args, so the fixture records no probe and the first Queue.take(probes) can time out.

Use a fixture path 

-        config: { ...CodexDriver.defaultConfig(), homePath: codexHome },
+        config: {
+          ...CodexDriver.defaultConfig(),
+          binaryPath: NodePath.join(codexHome, "missing-codex"),
+          homePath: codexHome,
+        },

Review comment at @apps/server/src/provider/Drivers/CodexDriver.test.ts around lines 756 - 757:
Update the CodexDriver test fixture configuration to set binaryPath to a controlled path under codexHome, while preserving the existing default configuration and homePath. This ensures the probe test does not resolve a Windows .cmd or .bat shim.
