* Tests for the codex-runtime router module (src/bin/codex-runtime-router.ts).
*
* Strategy: mirrors ccsxp-runtime.test.ts — invalidate require.cache before
* each test so the module re-evaluates with updated stubs and env state.
* Stub runCodexAuth and require('../ccs') via require.cache injection.
