添加com.helpscout:beacon依赖后构建失败，AGP版本适配疑问

在多模块Android项目中，仅向:common:base模块的build.gradle添加依赖com.helpscout:beacon:5.0.1后，构建失败，抛出如下错误：

项目未直接使用OkHttp，也未声明该依赖。项目使用AGP 8.2.0、Gradle 8.2，而Help Scout的beacon依赖使用AGP 8.0.2、Gradle 8.1。将AGP降级至8.1.1后问题解决，但不清楚：

• 为何仅该依赖引发问题？
• AGP版本差异是否为真正原因？
• 问题的本质是什么？

• 核心矛盾：BOM依赖的解析逻辑收紧
  OkHttp的okhttp-bom是一个平台（Platform）依赖，作用是统一管理OkHttp系列库的版本。AGP 8.2.x对依赖解析做了严格调整：它会校验每个依赖的"能力（Capability）"，明确区分"平台"和"普通库"。当项目用AGP 8.2.x时，运行时类路径要求所有依赖都是"普通库"，但okhttp-bom是平台，不符合要求，因此报错。

• 为什么只有这个依赖出问题？
  因为com.helpscout:beacon:5.0.1的依赖配置有误——它把okhttp-bom当成普通库直接引入，而不是用Gradle规定的platform()或enforcedPlatform()方式引入BOM。在AGP 8.1.x及更早版本，这种错误配置不会触发严格校验，所以能正常构建；但AGP 8.2.x收紧了规则，直接暴露了这个问题。

• AGP版本差异是直接诱因
  降级AGP到8.1.1后问题消失，本质是退回到了对依赖能力校验更宽松的版本，暂时绕过了beacon依赖的配置错误。但这不是根本解决办法，真正的问题出在beacon依赖本身的依赖声明上。

• 自定义BuildType的推波助澜
  错误日志里提到的staging自定义BuildType也是一个因素：AGP 8.2.x对自定义BuildType下的依赖属性传递校验更严格，而okhttp-bom没有携带BuildTypeAttr这类属性，进一步加剧了不兼容情况。
