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>

// Native (zero-serialization) C ABI. Each call delivers its result to the
|
|
// callback: on RET_OK, (msg, len) is the raw return value (for string-returning
|
|
// procs, the string bytes — not NUL-terminated; use len); on RET_ERR, (msg, len)
|
|
// is the raw error text. A `<name>_cbor` variant of each proc also exists for
|
|
// generic/cross-language callers that prefer a CBOR request/response.
