{.ffi.}/{.ffiCtor.} cover the async, context-handle, CBOR-marshaled path.
{.ffiExport.} covers the complementary case: a no-argument lifecycle/health
entry point a host loads with dlopen+dlsym and calls synchronously — no
context, no callback, no CBOR, the return value crossing the ABI directly.
Native Nim return types are bridged to the C ABI (int/bool -> int,
uint64 -> unsigned long long, string -> const char* kept alive in shared
memory; no-return -> void), and initializeLibrary() is injected so the Nim
runtime is up on first call — the host never invokes NimMain itself.
Fills the no-argument scalar case of the declared-but-unimplemented abi=c path.

nim-ffi
Allows exposing Nim projects to other languages
Example
examples/timer is now a self-contained Nimble project that imports nim-ffi directly.
Use cd examples/timer && nimble install -y ../.. && nimble build to compile the example.
