Type-Safe CLI Framework

Clipanion is a TypeScript-first framework for building robust and type-safe command-line interfaces (CLIs). It leverages TypeScript's powerful type system to define command arguments and options, providing compile-time validation and autocompletion, significantly reducing common runtime errors associated with CLI parsing. The package is currently at version `4.0.0-rc.4`, indicating active development towards a stable major release with a strong emphasis on modern JavaScript and TypeScript practices. A key differentiator is its zero runtime dependencies (beyond its peer dependency `typanion` for runtime type validation), resulting in extremely small bundle sizes. It integrates deeply with `typanion` to derive runtime validators directly from static TypeScript types, providing a seamless development experience for complex CLI applications. This approach contrasts with other CLI libraries that often rely on separate schema definitions or less integrated type checking.
