// Rewrites the VERSION constant in @pdsjs/core to match its package.json.
//
// changeset version bumps manifests but never touches source, and core carries
// its version as a literal because it cannot import package.json on Workers or
// Deno. Left to a human, the two drift: the constant sat at 0.7.0 across two
// releases, then at 1.0.0 through the 1.0.1 release. This runs as part of
// `npm run version-packages`; test/version.test.js is the backstop.
