- Call initializeLibrary() (setupForeignThreadGc) in the `.ffi.` request
wrapper and in add/remove_event_listener so a foreign (Go) caller thread
has an initialised Nim heap before any allocation ($reqTypeName /
$eventName / registry ops). Without it such a thread segfaults in the
allocator under GC pressure — the production unwrap SIGSEGV.
- recycleContext resets the event registry/queue + stuck flag on park so a
reused pool slot starts clean.
- ffiDtor doc/cleanup for the async recycle ABI.

A nim-ffi library is loaded into a foreign host (Go/Rust/...) that must
own OS signal handling; if the Nim runtime installs its own handlers it
clobbers the host's (e.g. Go's SIGSEGV -> sigpanic recovery, stack
growth, goroutine preemption), turning recoverable faults into hard
process crashes. The flag can only be set on the consumer's final build
command, so a dependency cannot inject it -- but it CAN refuse to
compile without it. Add a compile-time guard so any consumer that omits
-d:noSignalHandler fails the build with an actionable message instead of
crashing at runtime (the cause of a real status-go regression).
Standalone Nim binaries (nim-ffi's own tests) build with
-d:ffiAllowSignalHandler.

CBOR is the headline 0.2.0 feature, not 0.1.4: at v0.1.4 serial.nim was
still JSON/string-based, so the prior CBOR attribution was wrong. Also
complete the 0.2.0 scope (events, registry, codegen) ahead of tagging.
Date 0.1.4 by its last functional change (#14, 2026-05-13) rather than
the later changelog/version-bump commits, so the version reflects when
its code actually settled.

* 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).
