feat(codegen): native C++ typed event handlers

Adds the ergonomic native event surface to the C++ generator:
`node.On<Event>(std::function<void(const <Payload>&)>)` registers a native
listener; a per-event extern "C" trampoline reads the typed POD
(`fromC(*reinterpret_cast<const ::<Payload>*>(msg))`) and invokes the handler —
no CBOR. The handler is owned by the node (a `std::map` of `ListenerBase`) so
its address stays valid until `removeEventListener`.

The example registers `OnEchoFired` and receives a typed `EchoEvent` when Echo
fires it. Verified end-to-end and ASAN-clean.

With this the native C++ generator covers the full surface: requests
(scalar/string/bool/seq/Option/nested), typed struct returns, and typed events.
