Aligns the C++ generators with the C generator and the symbol naming: the
native (zero-serialization, same-process) wrapper is the bare `<lib>.hpp` and
the CBOR (inter-process) wrapper carries the `_cbor` suffix — mirroring the C
headers (`<lib>.h` / `<lib>_cbor.h`) and the `<name>` / `<name>_cbor` exports.
Previously native was `<lib>_native.hpp` and CBOR was the bare `<lib>.hpp`,
which is backwards from the symbol convention and would collide on the native
`<lib>.h` when both ABIs emit into one dir (ffiMode=both). With the flip, a
single `genbindings_cpp` run now drops `<lib>.hpp` + `<lib>_cbor.hpp` side by
side, exactly like c_bindings holds both `.h` headers.
Consumers updated to match: the CBOR cpp_bindings driver and the C++ e2e suite
include `*_cbor.hpp`; the native example includes the bare `<lib>.hpp`.
Validated: native example runs on `my_timer.hpp`; C++ e2e suite 19/19 on the
`_cbor.hpp` headers; check_bindings_cpp regen is deterministic.

Hammers one shared context from several threads, alternating the two ABIs of
the same library: the native path (EchoRequest struct in, typed EchoResponse*
back) and the CBOR path (encoded request in, CBOR map back), each verifying the
echoed message round-trips. Exercises the POD deep-copy/free on the way in, the
respPod deliver/free on the way out, and the request channel under contention.
Run plain or with SAN=address / SAN=thread. Clean at 6 threads x 1500 iters
(9000 calls per ABI) under both ASAN and TSAN — no leaks, use-after-free, or
data races.
