Jugg: Sub-3-Second Android Incremental Builds via Gradle-Bypass Sidecar Compilation

Tencent Music open-sources Jugg, an Android incremental build tool that achieves sub-3-second iteration by bypassing Gradle's fixed overhead via a sidecar compilation pipeline, using custom AAPT2 incremental linking, bytecode-level impact propagation, and JVMTI-based hot reload with hot-fix fallback, validated across 800k production builds.
