    CAMEL-23230: Force System.exit() in Main/KameletMain to ensure JVM 
terminates
    
    When durationMaxIdleSeconds triggers shutdown, the exit code is 0 (default
    durationHitExitCode), so System.exit() was skipped and non-daemon threads
    from components like RabbitMQ kept the JVM alive.
    
    - Always call System.exit(code) in Main.main() and KameletMain.main()
      after run() returns, consistent with camel-spring-main which already
      does this unconditionally
