Combining them into a single Gradle invocation caused :amethyst:packagePlayBenchmark to fail inside AGP's IncrementalSplitterRunnable worker — both variants share packaging state in one task graph and the benchmark leg trips on it. The old workflow always ran these as two separate `./gradlew` calls. Match that pattern. They still run on the same runner with a warm Gradle cache, so the compilation savings from sharing quartz/commons with the test+packageDeb step are preserved; we only pay two Gradle startups, which is trivial.
