Android Compose崩溃异常：需先调用layoutWithConstraints

这个崩溃的核心原因是：Compose文本组件的MultiParagraphLayoutCache在绘制阶段尝试获取文本布局结果时，发现布局约束还未被计算（即layoutWithConstraints方法未执行），从而抛出IllegalStateException。通常出现在自定义文本Modifier、或错误地在绘制阶段直接访问文本布局信息的场景。

解决方案： #

• 不要在绘制回调中直接获取文本布局结果
  如果你在自定义Modifier的draw操作里调用了getTextLayoutResult()，请将布局相关逻辑移到layout Modifier中执行，确保布局流程先于绘制完成。

• 检查自定义文本组件的生命周期
  若封装了自定义Text组件，确认没有在DrawScope等绘制阶段提前访问依赖布局的数据。Compose的布局（layout）流程必须在绘制（draw）之前完成，保证layoutWithConstraints被正确调用。

• 升级Compose版本
  部分旧版Compose存在布局与绘制时序的已知bug，升级到1.4.0及以上的稳定版可修复这类问题。
