/**
 * Debug script: verify builder class name when calling u01.r1.a("yibooo")
 *
 * Run on Mac:
 *   frida -U -n com.tencent.mm -l debug_builder_class.js
 *
 * This script will:
 *   1. Call u01.r1.a("yibooo") and print builder.getClass().getName()
 *   2. Print builder class hierarchy
 *   3. Test method calls via both builder.getClass() and Java.use("u01.q1")
 *   4. Check if setIntField("f", 0) / ("i", 4) causes any issue
