feat: Add initial Docker Compose setup for monitoring stack

This commit introduces a new `docker-compose.yml` file to set up a basic monitoring infrastructure.
It includes services for:
- Prometheus: For metrics collection and storage.
- Alertmanager: For handling and routing alerts.
- Grafana: For data visualization and dashboarding.

This setup provides a foundational stack for observing system health and performance.
