refactor(actors): consolidate foundation module into actor_system crate

* Remove legacy foundation module and its components, including adapters, health monitoring, and metrics.
* Update actor imports and references to utilize the actor_system crate exclusively.
* Enhance documentation to reflect the new architecture and actor organization.
* Ensure backward compatibility by maintaining necessary interfaces during the transition.

This consolidation streamlines the actor architecture, reduces code duplication, and leverages the production-ready actor_system crate for improved maintainability and performance.
