DESCRIPTION: This pull request introduces a testing framework for the Rust components of the Cap desktop application, addressing issue #184.

Key Changes: Testing Infrastructure: A new testing setup has been integrated into the src-tauri directory. This uses Rust’s built-in testing capabilities. Initial Tests: Implemented initial tests for the core recording functionalities: start_recording stop_recording Test Command: Added a new script test:desktop to package.json, which can be run with pnpm test:desktop to execute the Rust tests. Scalability: The testing structure is organized to be easily scalable for future tests covering more functions like copy_to_clipboard, save_file, and render_file. This provides a solid foundation for ensuring the quality and correctness of the Rust backend of the desktop application.
