Add readiness check in daemon context 🚀

- Modified `daemon.py` to include `wait_for_readiness()` function.
- Ensures the daemon is fully operational after spawning.

This change enhances the reliability of the daemon by confirming it's ready
before proceeding. This minimizes potential errors due to asynchronous
operation states. 📈
