This change significantly expands the monitoring capabilities of Nanomon by allowing users to leverage existing Prometheus infrastructure for health checks. Users can now create monitors that execute PromQL queries and evaluate the results as pass/fail conditions. This integration enables more sophisticated monitoring scenarios and better integration with existing observability stacks. The changes are additive and should not impact existing monitor types or functionality.
