Added cache Worker Manager to handle cache update

[petruki]

This pull request introduces a new worker-based system for scheduled cache updates in the src/helpers/cache module. The main goal is to offload periodic cache refresh operations to a background worker thread, improving performance and reliability. The update includes the implementation of a worker manager, the worker itself, integration into the cache class, and new unit tests to verify the functionality.

Worker-based scheduled cache updates:

• Added a new CacheWorkerManager class (worker-manager.js) that manages a background worker thread for periodic cache updates, including event handling, status tracking, and error management.
• Implemented a new worker script (worker.js) that connects to the database, checks for domain updates at a configurable interval, and communicates with the main thread to synchronize cache state.
• Integrated the worker manager into the Cache class (index.js), adding methods to start and stop scheduled updates, handle worker events, and synchronize cache versions between the worker and the main process. [1] [2]

Testing and configuration:

• Added and updated unit tests in cache.test.js to verify scheduled cache updates, cache version synchronization, and worker lifecycle management. [1] [2] [3]
• Updated SonarQube configuration to exclude the new worker file from code coverage analysis.
