Solar2DBuilder Linux 2026.3728.1

Linux build of Solar2DBuilder for CI/CD Android APK builds.

Built from Solar2D 3728 open source with Linux Android patches. Package version: 3728.1 (the tarball keeps the upstream build number in its name).

Packaging: repacked from 2026.3728 — same binary, Android template patched

Android template patch: template/app/build.gradle.kts now reads build.settings android.targetSdkVersion (falling back to the template default) and uses compileSdk = maxOf(default, targetSdk), so an app can declare a target platform newer than the template's hardcoded one (needed for Google Play's API-level floor).
