Deliberately a plain constant rather than a build-time define: the parity
harness and the whole test suite import src/ directly through tsx, where a
define'd global is undefined, so the version would silently degrade under
exactly the tooling this repo leans on hardest. A unit test asserts this
matches package.json, which makes drift fail the build instead of shipping.
The package version, in one place.
