fix(codegen): emit 3-arg async destroy ABI in C++/Rust bindings

The recycle/async-destroy work changed the Nim `ffiDtor` export from
`int destroy(ctx)` to `int destroy(ctx, callback, userData)`, but the C++
and Rust generators still emitted the 1-arg signature. Foreign callers
therefore passed only `ctx`; inside Nim, `callback`/`userData` held
uninitialised register garbage. `requestRecycle` stored the garbage
callback and the recycle handler later invoked it — a jump through a wild
pointer that segfaulted in every C++ E2E / ASan / TSan job (the crash
surfaced at teardown, after each test's assertions had already passed).

Generate the 3-arg ABI and have the destructor/Drop block on the recycle
callback via the existing sync-call helper, so the pool slot is fully
drained and parked before the handle goes away — otherwise rapid
create/destroy churn (StressShortLivedPerThreadContext, ThreadedHammer)
could outrun the recycle and exhaust the pool.

timer example

This example is a self-contained Nimble project demonstrating how to import nim-ffi and use the .ffiCtor. / .ffi. abstraction.

Usage

Change into the example directory:
```
cd examples/timer
```
Install the local ffi dependency:
```
nimble install -y ../..
```
Build the example library:
```
nimble build
```

Generate bindings:

nimble genbindings_rust
nimble genbindings_cpp

Rust example clients

The Rust client lives in examples/timer/rust_client.

Run the sync example:

cd examples/timer/rust_client
cargo run --bin rust_client

Run the Tokio example:

cd examples/timer/rust_client
cargo run --bin tokio_client

C++ example

The generated C++ example lives in examples/timer/cpp_bindings.

Build and run it with:

cd examples/timer/cpp_bindings
cmake -S . -B build
cmake --build build
./build/example
