Enhance testing framework by introducing a unified test runner in run-all.js, allowing for streamlined execution of multiple test scripts. Update package.json to include new test commands for individual test scripts and the consolidated runner. Add comprehensive test cases for list_files, read_file, and ripgrep functionalities, improving overall test coverage and error handling.
