src/index.ts imports package.json for VERSION and bin/quak.ts passes
VERSION to commander, so package.json is the only place the version is
written. tsc copies package.json to dist/package.json, so the import
resolves from the built output; script/build runs the built CLI with
--version to prove it. A test checks VERSION and quak --version against
package.json.
