test(e2e): native + CBOR concurrency stress harness
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.
