The C++ wrapper speaks CBOR, but after the native/CBOR split it still called the
bare `<name>` symbols — which are now the *native* (typed-args) entry points, so
every C++ call hit the wrong ABI and the C++ e2e failed 19/19 (also reddening
the ASan/TSan jobs, which run the same suite). Point the generated extern
declarations and call sites at `<name>_cbor` for `{.ffi.}` procs and the ctor;
the destructor has no CBOR variant and stays bare. Regenerated the timer and
echo C++ bindings. C++ e2e back to 19/19.
