子弹图组件设置legend: false; 但是图例不关闭，显示title

最新版本的@antv/g2plot的Bullet组件

Start by reproducing the Bullet component configuration described in the issue with legend set to false. Trace how the Bullet component handles the legend and its title, then verify that both are hidden when the option is disabled. No source file or test path is named, so locating the relevant implementation and regression test will require repository exploration.
