    fix: use WARNING instead of WARN in SimpleBuildEventListener log output
    
    LogLevel.WARN.name() produces 'WARN' but Maven's traditional console
    format uses '[WARNING]'. Map the level name in renderLevel() so that
    integration tests expecting '[WARNING]' in the output continue to pass.
