Motivation: The codebase needs to compile with both Scala 3.3.x (current production) and Scala 3.8.4 (forward compatibility). Scala 3.8 introduces new deprecation and syntax warnings that need to be suppressed to maintain clean compilation. Modification: - PekkoDisciplinePlugin: add -Wconf rules for Scala 3.8 deprecation warnings (private[this], = _ initializers, context bounds) in both main and test scopes - Jdk9/JdkOptions: update JDK-specific compiler options - SbtMultiJvmPlugin: minor formatting fix Result: Scala 3.8 warnings are suppressed via -Wconf, allowing clean compilation without breaking -Werror on both 2.13 and 3.x. Tests: Not run - build config only References: None - proactive Scala 3.8 forward compatibility
