OpenRewrite moves its releases off Maven Central to Moderne's authenticated Code Genome Project

OpenRewrite's documentation now says its modules and recipes are distributed through the Code Genome Project, the repository run by Moderne, the project's main sponsor and contributor, rather than being published to Maven Central. Every download requires authentication, so builds must add the repository and supply a username and token, Maven Central stays configured only so OpenRewrite's transitive dependencies still resolve, and the Maven and Gradle plugins are no longer published to the Gradle Plugin Portal. The module table shows the licensing split in the same release: core modules and the original language bindings such as Java, Groovy, Kotlin, XML, Properties and YAML remain Apache-2.0, while newer language modules for JavaScript and TypeScript, Python, Ruby, Scala, Android and mainframe, along with substantial third-party recipe libraries, are under the Moderne Source Available License. The project's recipe catalog says access is free for open source projects.
