- Add Proof of Concept (PoC) for executing JavaScript scripts fetched remotely. - Integrate `Black::GetProfileInfoScript` logic into a JS version with fallback to C++ on errors. - Extend `ScreenXmlParser` with additional JS-to-C++ bridge methods. - Update `config.ini` for scripting configuration. - Ensure scripts are securely fetched with SHA-256 validation and use an atomic caching mechanism. - Add developer tools for debugging JS scripts and enable easier script updates without app re-deployment.
