* 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).

Rust Bindings for nim-timer

Purpose

This folder contains auto-generated Rust bindings (the my_timer crate) for the my_timer Nim library. It is generated from ../timer.nim and provides:

src/lib.rs: Main library exposing high-level Rust types and the MyTimerCtx API
src/api.rs: High-level async/sync wrapper around the FFI
src/ffi.rs: Raw extern "C" declarations for the Nim library
src/types.rs: Serializable Rust types matching the Nim FFI types
build.rs: Build script that compiles the Nim library to libmy_timer.dylib (or .so/.dll)
Cargo.toml: Package manifest with serde and serde_json dependencies

How It's Generated

Generate or regenerate these bindings by running from the parent directory:

cd examples/timer
nimble genbindings_rust

This command:

Invokes the Nim compiler with -d:targetLang:rust flag
Triggers genBindings("examples/timer/rust_bindings", "../timer.nim") in timer.nim
Creates/updates the generated binding files

Using as a Dependency

The rust_client example consumes this crate:

[dependencies]
my_timer = { path = "../rust_bindings" }

Do Not Edit

The generated files in this folder are overwritten each time nimble genbindings_rust runs. Any manual changes will be lost.
