fix(bugcollect): 使用 manifest meta-data 传递 buildId，修复 namespace/applicationId 不一致导致反射失败

BuildConfig 反射方案在 applicationId 与 namespace 不同时（如 shijiaobao flavor）会抛出
ClassNotFoundException 导致 buildId=null。改为通过 manifestPlaceholders 注入 xuqmBuildId，
SDK 从 PackageManager.getApplicationInfo(GET_META_DATA) 读取，彻底绕开包名歧义。
