How rxnt/json-rules-engine-simplified works

This is a small JSON rules-engine library. A caller supplies rules and form data to Engine; Engine optionally validates rules against a schema, evaluates conditions, and resolves matching events. Boolean and field predicates perform the condition checks, while utilities support nested-field access and schema references. The map reflects the sampled runtime sources and README; it does not infer event handling beyond returning matched event objects.
