Fix: Update e2e test to match detected platform

- Updated `test/scheduler-preflight-lock.e2e.test.mjs` to expect `detectPlatform() || 'codex'` instead of hardcoding `'codex'`.
- This ensures the test passes when running in environments where the platform is correctly detected (e.g., 'jules'), aligning with the changes made in the previous commit.
