CngxFilterBuilderValueEditorContext

Context object handed to the consumer template when the cngxFilterBuilderValueEditor slot resolves. Mirrors the data the default native / component-outlet branches consume - value is the current expression value, fieldDef carries the field metadata, setValue is the row's write-through callback, and expression exposes the full node for consumers that need the operator alongside the value - e.g. a range editor that toggles UI on the builtin 'between' operator (opt-in: expose it per field via FilterFieldDef.operators, it evaluates against a [min, max] value).
