Subject: [PATCH] feat: add application container and event classes for user
 and torrent uploads

- Introduced a new Container class extending the Illuminate Container for application-specific functionality.
- Added TorrentUploaded and UserRegistered event classes to handle torrent uploads and user registrations, respectively.
- Implemented methods for retrieving service instances and checking service existence in the Container.
- Established a structured approach for event data encapsulation with readonly properties and getter methods.

This update enhances the application's architecture by integrating a custom container and event-driven design, improving maintainability and extensibility.
