Refactor CI workflow and enhance protocol handler in adapter-electron

Browse Source 
- Updated GitHub Actions workflow to streamline testing and type checking processes.
- Consolidated test steps and improved error handling for better clarity.
- Enhanced protocol handler functions in setupHandler.js to support additional features and security measures.
- Added new utility functions for file handling and path validation to improve robustness.
- Updated integration tests to cover new functionality and ensure proper request handling.
