Summary: **Lint Issue:** ANDROIDLINT FieldsBelowInit warning on line 347. The `nativeModules` property was declared below the init block. The lint warns that fields declared after init blocks can lead to initialization order issues in Kotlin, where the field might not be available during the init block execution. **Fix:** Moved the `nativeModules` computed property declaration to before the init block, alongside other property declarations. Since this is a computed property (getter only), there's no actual initialization order issue, but placing it before the init block follows Kotlin best practices and avoids confusion.

Summary: **Lint Issue:** ANDROIDLINT FieldsBelowInit warning on line 480. The `eventDispatcher` property was declared below the init block. The lint warns that fields declared after init blocks can lead to initialization order issues in Kotlin, where the field might not be available during the init block execution. **Fix:** Moved the `eventDispatcher` computed property declaration to before the init block, alongside other property declarations. Since this is a computed property (getter only) that returns `fabricUIManager.eventDispatcher`, there's no actual initialization order issue, but placing it before the init block follows Kotlin best practices and avoids confusion.

Summary:
**Lint Issue:** ANDROIDLINT KotlinGenericsCast warning on line 361.
The `getNativeModule` function casts `turboModuleManager.getModule(nativeModuleName)` to generic type `T?`. The lint warns that casts to erased Kotlin generic type references are only checked at compile time, and at runtime, casts to type arguments of a generic function are unchecked due to type erasure.
**Fix:** Added `SuppressLint("KotlinGenericsCast")` annotation to the function. The existing `Suppress("UNCHECKED_CAST")` only suppresses the Kotlin compiler warning, not the AndroidLint warning. This cast is intentional and unavoidable given the API design where callers specify the expected return type.
