Pull request overview

Adds curryWith helpers for java.util.function BiPredicate/BiFunction/BiConsumer types (which lack Closure.rcurry), plus from lifters that produce hybrid SAM+Closure values usable with both SAM-accepting JDK/DGM APIs and Closure-accepting DGM APIs.

Changes:

• New org.apache.groovy.util.Lambdas with curryWith overloads returning bare Predicate/Function/Consumer.
• New org.apache.groovy.util.Closures with from(...) lifters, curryWith(...) composing on Lambdas.curryWith, and three nested hybrid classes (PredicateClosure, FunctionClosure, ConsumerClosure) extending Closure and implementing the matching SAM.
• New tests (LambdasTest, ClosuresTest) and a new "Currying functional interfaces" section in core-closures.adoc.
