* Measures cold-start time with and without the Baseline Profile so the win is quantifiable.

*

* Run it with:

* ```

* ./gradlew :androidApp:benchmarkGoogleReleaseBaselineProfile

* ```

*

* Compare `startupCompilationNone` vs `startupCompilationBaselineProfiles` in the output: the delta

* is the startup improvement the shipped profile buys. `Partial(Require)` fails loudly if the

* profile is missing, so this also guards against a release that silently dropped it.
