{.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.

* rust examples: sync main.rs + tokio main.rs demoing the listener API
Adds two bundled examples to the generated Rust crate:
- examples/main.rs: sync flow using std::sync::mpsc to bridge a typed
on_echo_fired listener into main + a wildcard add_event_listener
that uses decode_event_payload::<EchoEvent>(envelope) for the
matching event id.
- examples/tokio_main.rs: same shape via #[tokio::main] +
tokio::sync::mpsc.
Bumps generateCargoToml to ship `[dev-dependencies]` with tokio's
`rt-multi-thread` + `macros` features so the bundled examples can use
#[tokio::main] without polluting the library's runtime profile.
Run with `cargo run --example main` (set DYLD_LIBRARY_PATH=<repo> on
macOS until build.rs emits an rpath).

* protect against mem leak in case of failures sending requests to ffi thread
* better cleanup if failures in createFFIContext
* avoid dangling cstring in handleRes under ARC/ORC
* better resource cleanup in destroyFFIContext
* invoke onNotResponding if failure in destroyFFIContext
* correct seq copy in alloc
* make sure the lock is init before cleanUpResources
* better possible exception handling in processReq
* guard allocSharedSeq if given seq is empty
* enhance error handling in ffi_context
