T8b949e/**

* Generates a Baseline Profile for the app's critical user journey.

*

* Run it with:

* ```

* ./gradlew :androidApp:generateGoogleReleaseBaselineProfile

* ```

*

* The [androidx.baselineprofile] plugin on `:androidApp` drives this against the auto-created

* `nonMinifiedRelease` variant and merges the result into

* `androidApp/src/googleRelease/generated/baselineProfiles/`. Commit that output so release builds ship

* it.

*

* The journey is intentionally minimal (cold start → first frame) because CI has no paired radio.

* Extend it with post-connection screens (node list, map, message thread) once a fake transport or

* connected device is available in the harness — the more representative the journey, the better the

* profile.
