This PR adds compile-time regression tests for KStream API generic bounds (KAFKA-8035).
Each KStream method is tested with both a lambda expression and an anonymous class implementation. If the generic bounds on any method were incorrect, the Java compiler would reject the lambda form — so these tests act as regression guards for future API changes.
Methods covered: filter, filterNot, selectKey, map, mapValues (ValueMapper + ValueMapperWithKey), flatMap, flatMapValues (ValueMapper + ValueMapperWithKey), foreach, peek, merge, method references.
26 tests, all passing.
