📝 Original Issue Description

   Issue task:
  Description

The Actor Model is a concurrency paradigm in which independent “actors” encapsulate state and behavior, interacting solely through asynchronous message passing. This approach avoids shared mutable state and promotes highly scalable, loosely coupled systems. Actors can create new actors, send messages to other actors, and handle messages they receive.

Key Elements
Actors: Independent units that manage their own state and process messages.
Message Passing: Non-blocking communication between actors; no direct method calls or shared variables.
Isolation: Each actor’s state is private, limiting concurrency issues.
Supervision: Some actor frameworks use a hierarchy where parent actors supervise the lifecycle and errors of child actors.
