feat(qjs): introduce RAII-based QuickJS bindings

Wrap the QuickJS C API with a modern C++ interface featuring:

• RAII resource management
• value and move semantics for JSValue ownership
• exception-based error handling
• type-safe value conversion helpers
• object and array access utilities

I'd say there's zero chance of this getting merged, for several reasons, one of them being that your approach is incompatible with -fno-exceptions builds.

More generally, I don't think we're open to adopting an opinionated C++ API.

Agreed. Plus, since this doesn't need any internals I can live as a standalone project.
