feat(codegen): native (non-CBOR) C++ generator — core
A native C++ binding generator (`cpp_native.nim`), the C++ counterpart of the C
and Go native paths and companion to the CBOR `cpp.nim`. It emits
`<lib>_native.hpp`: an idiomatic C++ struct + `toC`/`fromC` per `{.ffi.}` type,
and a `<Lib>Node` class whose methods marshal typed args into / read typed
struct returns out of the native ABI (`<name>` entry points + flat C structs in
`<lib>.h`) — zero serialization. Wired into genBindings under
`targetLang=cpp` + `-d:ffiMode=native`; emits the native C header alongside so
the binding is self-contained. Task: `genbindings_cpp_native`.

First cut covers scalar/string/bool/nested-struct fields (create/version/echo);
seq/Option params are `// SKIPPED`, and native typed events are next. Filename
is `_native.hpp` for now to coexist with the CBOR `.hpp` (rename is a follow-up).

Verified end-to-end: the generated example builds and round-trips a typed
EchoResponse (`make run`).
