feat: add Gradle cache to Android release builds (#251)

Introduce androidBase() and firebaseBase() helpers that wrap setup() with
the Gradle named-cache volume, mirroring the pattern already used in
BuildAndroidDebugApks(). Use these in BuildAndroidRelease(), setupKeystore(),
and BuildAndroidDebugApks() so Gradle dependencies survive Dagger
execution-cache misses instead of being re-downloaded on every source change.
