## Summary
- `android/app/build.gradle.kts` used `kotlinOptions { jvmTarget = JavaVersion.VERSION_17.toString() }`, which Kotlin 2.x treats as a compilation error ("Using jvmTarget: String is an error")
- Replaced with the `compilerOptions` DSL using `org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_17`
## Test plan
- [x] Confirmed root cause from CI run #1316 logs: `e: .../build.gradle.kts:20:9: Using 'jvmTarget: String' is an error`
- [ ] CI deploy workflow should now pass the Android bundle build step
Closes #351
