/**
 * grafana_create_alert tool
 *
 * Creates Grafana-native alert rules via the Unified Alerting provisioning API.
 * The agent composes PromQL conditions — Grafana's alerting engine evaluates
 * them on schedule and notifies via configured contact points.
 *
 * Auto-creates a "Grafana Lens Alerts" folder if no folderUid is specified.
 *
 * Before creating the rule, the expression is dry-run against the datasource
 * to validate it. The result is included as `metricValidation` in the response.
 * The alert is always created regardless — the metric may not have data yet.
