Singleton
Annotation: Singleton
Marks a class which participates in injection (DI) as a singleton; singletons are classes with the constraint that only one instance may exist at runtime. In injected contexts, the singleton lifecycle is managed by the DI container.
On JVM platforms, this annotation behaves like a standard Jakarta Singleton annotation: https://jakarta.ee/specifications/dependency-injection/2.0/apidocs/jakarta/inject/singleton
