Gradle Build System

Rule 1: Version Catalog is the only place for versions

# gradle/libs.versions.toml — single source of truth
[versions]
agp = "8.5.2"
kotlin = "2.0.21"
ksp = "2.0.21-1.0.25"

[libraries]
androidx-core-ktx = { group = "androidx.core", name = "core-ktx", version.ref = "coreKtx" }

[plugins]
android-application = { id = "com.android.application", version.ref = "agp" }
kotlin-android = { id = "org.jetbrains.kotlin.android", version.ref = "kotlin" }
