buildVersion property
Version string reported by the Rust core.
The simplest possible round trip -- a synchronous, argument-free call
returning a string -- so it doubles as the smoke test that the whole
chain is wired up: build hook resolved the library, @Native bound the
symbol, and a value came back across the FFI boundary.
Throws UnsupportedError on web.
Implementation
static String get buildVersion => impl.buildVersion();
