refactor(idlewatcher): improve container readiness handling and health check logic

- Simplified the wakeFromHTTP and wakeFromStream methods by removing unnecessary loops and integrating direct checks for container readiness.
- Introduced a waitForReady method to streamline the waiting process for container readiness notifications.
- Enhanced the checkUpdateState method to include timeout detection for container startup.
- Added health check retries and logging for better monitoring of container state transitions.
