Tiny CLI Argument Parser

cli-nano is a lightweight library for building command-line interfaces (CLIs) in Node.js, offering functionality similar to `yargs` or Node.js's built-in `parseArgs()`. It supports parsing positional arguments, flags, and options with robust configuration capabilities. The current stable version is 1.2.2, with releases occurring fairly frequently, often including minor bug fixes and features, sometimes with breaking changes within minor versions as seen with v1.2.0 and v1.0.0. Its key differentiators include a minimal footprint, zero external dependencies, and extensive configurability for defining argument types, aliases, defaults, and generating help output, making it a powerful alternative to heavier CLI libraries while providing more features than the native `parseArgs()` method. It is designed for Node.js environments and ships with TypeScript types for enhanced developer experience.
