# Cloud Agent install script for the FromChat KMP client.
#
# Idempotent: safe to run repeatedly. Prepares everything needed to build the
# Android app (`:app:android:assembleDebug`) and compile the shared module
# (`:app:shared:compileAndroidMain`) on a headless Linux Cloud Agent VM:
#   1. A JDK 17+ (uses the system JDK; installs OpenJDK 21 only if none is found).
#   2. The Android SDK (command-line tools + required platforms/build-tools).
#   3. Git-ignored local secrets the Gradle build reads at configuration time:
#      debug/release keystores, keys/keystore.properties, and a placeholder
#      google-services.json (Firebase config; the checked-in build applies the
#      google-services plugin). These are throwaway, non-secret dev values.
#   4. local.properties pointing Gradle at the SDK.
#
# iOS targets (compileKotlinIosArm64 etc.) require macOS + Xcode and cannot be
# built on this Linux VM; only the Android/shared-android surface is prepared.
