Try new features from Kotlin 2.4: context parameters and backing fields

Context params 

```kotlin
context(CoroutineScope, Logger)
fun syncOfflineData(documentId: String) {
    launch { logEvent("Sync initiated for $documentId") }
}
```

Backing fields

```kotlin
val uiState: StateFlow<UiState>
    field = MutableStateFlow(UiState.Loading)
```
