refactor(codegen): reconcile Rust crate names with the native/cbor convention

Aligns the Rust crate names with the C generator and the symbol naming: the
native (zero-serialization, same-process) crate is the bare `<lib>` and the
CBOR (inter-process) crate carries the `_cbor` suffix — mirroring `<lib>.h` /
`<lib>_cbor.h` and the `<name>` / `<name>_cbor` exports.

Previously the native crate was `<lib>_native` and the CBOR crate was the bare
`<lib>`, which is backwards from the symbol convention. Only the Cargo package
name changes; the linked dylib stays `lib<lib>.dylib` (the `#[link]` name and
build.rs are untouched).

Consumers updated: rust_client depends on `my_timer_cbor` and imports from it;
the native demo imports from the bare `my_timer`.

Validated: rust_client builds against the renamed CBOR crate; the native demo
round-trips version / echo / event / complex / schedule against the bare crate;
check_bindings_rust regen is deterministic.

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]
# CBOR (inter-process) crate carries the `_cbor` suffix; the native crate is the bare `my_timer`.
my_timer_cbor = { 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.
