Subject: [PATCH] chore: configure :app module gradle build
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Compose with Material 3 Expressive (1.5.0-alpha21 explicit override of
BOM stable), Hilt 2.59.2 + KSP 2.3.9, DataStore. Single-module project.
JVM 17 + Kotlin 2.3.21. JUnit Jupiter 6.1.0 unified (jupiter + platform).
testOptions opts into JUnit Platform so JUnit5/6 tests get discovered.

Note: kotlin-android plugin removed — AGP 9.0+ provides built-in Kotlin
support and the plugin now hard-errors when applied alongside AGP 9.x.
kotlin-compose plugin retained (separate Compose compiler plugin).
