Subject: [PATCH 01/15] Add CompilerPlugin platform support in Scala models
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Introduce CompilerPlugin in Platform.scala
- Update BinaryVersion.toString to handle CompilerPlugin
- Update all platform matches in Artifact.scala to explicitly handle CompilerPlugin
- Throw UnsupportedOperationException where features aren’t implemented
- Add unit test for creating Artifact with CompilerPlugin
- Lints clean
