feat: add local test executable and improve JSON string escaping - Added option to build a local test executable for value assignments. - Enhanced JSON string formatting by escaping special characters. - Updated README with build instructions and prerequisites. - Modified .gitignore to include .vscode directory. - Added file read/write tests in format_test.cpp. - Refactored value assignment logic to reduce code duplication.
