docs: mark Logging as complete, Domains as in-progress in feature table

Full logging stack (#233, #221, #220) is now merged — update Logging
from ⚠️ to ✅. Domain binding (#231) is actively in development —
update Domains from ❌ to ⚠️ and rewrite the section to reflect
current state with a link to the OpenFeature Domains docs.

 ### Logging
 
-Logging customization is not yet available in the Kotlin SDK.
+The Kotlin SDK includes a `LoggingHook` and a structured `Logger` interface. Pass a `Logger` implementation when constructing `LoggingHook`, then register it as a hook to capture flag evaluation events. Without a `Logger`, `LoggingHook` uses a no-op logger by default and produces no output.
 
-It is possible to write and inject logging `Hook`s to log events at different stages of the flag evaluation life-cycle.
+```kotlin
+// use a platform-specific logger (Android, JVM, iOS, JS, Linux)
+val logger = LoggerFactory.getLogger(tag = "MyApp")
+OpenFeatureAPI.addHooks(listOf(LoggingHook(logger = logger)))
+```
 
 ### Domains
 
-Domains allow you to logically bind clients with providers.
-Support for domains is not yet available in the Kotlin SDK.
+[Domains](https://openfeature.dev/docs/reference/concepts/domain) allow you to logically bind clients with providers, enabling multiple provider configurations within the same application.
+Support for domains is currently in development.
