Complements the CBOR C++ bindings (../cpp_bindings) with the native path: a C++
program that links the library and calls the native `<name>` ABI directly,
passing {.ffi.} structs by value and reading typed struct returns
(EchoResponse) from the callback — no CBOR, no tinycbor. An RAII TimerNode
wrapper bridges the async FFI-thread callback to a synchronous API via
std::future. README spells out native (same-process) vs CBOR (IPC). Verified
end-to-end with `make run`.
