Two things had to change alongside the version: * zio-sbt-ecosystem defaults javaPlatform to 11 and passes -release:11, which Scala 3.9 rejects. Set it to 17 on every module. * Scala 3.9 no longer accepts passing the Output positionally to `returning`, which takes it as a context bound. Dropping the explicit argument alone breaks Scala 2.13, where the local decoder and the imported ScriptingSpec.simpleStringOutput are then both eligible and ambiguous, so name the local one so it shadows the import instead.
