POC: Unified WebSocket Library for Cross-App Integration

[edloidas]

Develop a proof of concept (POC) for a standalone WebSocket library designed to unify and standardize WebSocket usage across all applications.
The library should provide a flexible and intuitive interface, wrapping the native WebSocket connection with its own set of consistent functions and event handlers.
Initially, the library will be tested and integrated into the main large application (this, app-contentstudio), with the goal of simplifying WebSocket handling and ensuring a uniform approach to connection management, events, and data communication across projects.

Moved core parts of WebSocket implementation from AI Content Operator and made it more generic. That code will be used in future tasks, beyond this POC.
