@groovy.util.logging.Slf4j @groovy.transform.CompileStatic class GroupTupleByOp extends java.lang.Object
Groups channel items by closure-extracted keys. This operator implements grouping logic similar to Nextflow's groupTuple, but uses a closure to dynamically extract the grouping key from each item instead of requiring tuple indices.
