The C codegen already emitted `my_timer.h` / `my_timer_cbor.h`, but the example had no runnable driver. Add `example.c` exercising the native ABI end-to-end (ctor with a struct param, string-returning version, struct-param echo, and a deeply nested ComplexRequest), plus a Makefile that builds the Nim dylib from the repo root — where the vendored Nimble deps resolve — and links the driver. Native is the same-process path; the companion CBOR headers are for crossing a process/machine boundary (see the forthcoming ipc example). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
