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.

Splits the Rust codegen the way C++ is split: rename `rust.nim` -> `rust_cbor.nim`
(CBOR) and add `rust_native.nim` (native). Dispatch on `targetLang=rust` now
honours `-d:ffiMode` (native/cbor); the crates share file names so each mode
writes its own dir (rust_bindings vs rust_native_bindings).
`rust_native.nim` emits a `<lib>_native` crate — the Rust analogue of
`cpp_native`: `#[repr(C)]` POD mirrors + `extern "C"` native entry points
(ffi.rs); idiomatic structs with `to_c`/`from_c`, a holder owning the CStrings
for the call (types.rs); and a `<Lib>Node` whose methods marshal typed args in /
read typed struct returns out, blocking via std mpsc (api.rs).
First cut: scalar/string/bool/float/nested-struct fields (create/version/echo);
seq/Option params are SKIPPED, native events next. Verified end-to-end — the
generated crate builds and the demo round-trips a typed EchoResponse. Tasks:
genbindings_rust (CBOR), genbindings_rust_native.
