chore: Add Android SDK project skeleton

Build infrastructure for Android SDK library:
- Gradle build configuration with Kotlin 2.2, Android Gradle Plugin 8.13
- Version catalog with dependencies (Ktor, kotlinx.serialization, testing)
- Code quality: Detekt, ktlint, JUnit 5 + Robolectric
- Maven Central publishing configuration
- Sample app module structure
- Minimal stub files for compilation
