Netdata alert migration

This skill migrates alerting rules to Netdata's health engine. The source is almost always a Prometheus-style rule set: VictoriaMetrics vmalert, Prometheus itself, Thanos Ruler, or Mimir/Cortex. They all consume the same alerting-rule YAML and the same PromQL/MetricsQL query language, so one method covers all of them. Examples here lead with vmalert because that is the common request.

The work is not a transpile. The two systems have different models: a PromQL rule queries arbitrary time series by metric name and label matchers, while a Netdata alert attaches to a chart context and aggregates that chart's dimensions over a time window. There is no one-to-one converter. This skill is a translation methodology, and a large part of it is recognizing what you should not translate at all.
