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.
